It begins in Aachen at the German–Belgian border and ends near Kassel. Before the German unification it was an unimportant provincial motorway but after this event it became an integral part of the German highway system. The A 44 is a highly frequented link between the Rhine-Ruhr-Area and the new German states, especially Thuringia, and by proxy, eastern European states like Poland and Ukraine.

Bundesautobahn 31 (translates from German as Federal Motorway 31, short form Autobahn 31, abbreviated as BAB 31 or A 31) is a German Autobahn that connects the coast of the North Sea near Emden to the Ruhr area. It is also known as Emsland-Autobahn or East Frisian Skewer. It was completed in December 2004. Construction was in part made possible by a unique method of financing: individuals, companies, towns, counties and the Netherlands donated money to accelerate the project.

Bundesautobahn 8 (translates from German as Federal Motorway 8, short form Autobahn 8, abbreviated as BAB 8 or A 8) is an autobahn in southern Germany that runs 497 km (309 mi) from the Luxembourg A13 motorway at Schengen via Neunkirchen, Pirmasens, Karlsruhe, Stuttgart, Ulm, Augsburg and Munich to the Austrian West Autobahn near Salzburg. The A 8 is a significant East-West transit route. Its construction began in March 1934 during Nazi rule as a Reichsautobahn, the section between Karlsruhe and Salzburg having been completed by the time road works were discontinued in World War II. Although most parts have been modernized and extended since, significant sections remain in their original configuration from the 1930s - 2+2 lanes, no emergency lanes, steep hills and tight curves. In combination with today's traffic this makes the A 8 one of the most crowded and dangerous autobahns in Germany. Especially in the wintertime the slopes of the Black Forest, the Swabian Alb near Aichelberg, as well as the Irschenberg become bottlenecks when heavy trucks crawl uphill. Modern sections with 3+3 lanes and more are e.g. (2016): Karlsruhe - Pforzheim-North, Pforzheim-South - Stuttgart - Mühlhausen, AK Ulm/Elchingen - Augsburg - Munich-Eschenried, and AK Munich-South - AD Inntal. Other sections in Saarland, Rhineland-Palatinate and Munich have 2+2 in modern standard. Old standard or not completed sections are (2016): near Merzig (under construction), AK Neunkirchen - Zweibrücken (no emergency lanes yet), Enz crossing near Pforzheim (modernizing planned), Alb crossing Mühlhausen - Hohenstadt (planned), Hohenstadt - Ulm-West (under construction), Ulm-West - AK Ulm/Elchingen (planned) and AD Inntal - Salzburg (planned). At least, complete section Karlsruhe - Salzburg will be extended to 3 + 3 lanes.

It led around Schwerin and is now part of the A 14. An extension of the autobahn to the A 20 had been planned in 1992, but failed to be realized due to financial and environmental factors. The current extension will not be finished before 2009. The former A 241 never carried much traffic because Schwerin can be reached from the A 24, a much shorter connection. Also, Wismar could only be reached from the A 241 by driving through narrow avenues, so that the became the preferred route. More traffic can be expected to flow once the gap is closed and the junction Schwerin-Süd is finished. On August 24, 2006, the part between the Kreuz Wismar and the junction Jesendorf was opened for traffic. This 11 km long segment of the road cost over €50 million to construct. Once completed, the A 241 will be renumbered as part of the A 14.

The western segment has a length of 156 km (97 mi), the part in the east is 429 km (267 mi) long. Works to continue the A 4 are in progress, but currently no plans exist to fill the gap completely. The A 4 starts north-west of Aachen, where the Dutch A76 enters Germany. Initially it is 2 lanes each way with no speed limit. From Kreuz Aachen to Düren and from Kerpen to Refrath (between Refrath and Köln-Merheim westbound the hard shoulder is the 3rd lane and only open at peak times) it has 3 lanes each way. Between Kreuz Köln-West and Kreuz Heumar it forms the southern part of the Cologne Beltway (Kölner Autobahnring). The whole rest of the section between Kreuz Aachen and Kreuz Köln-West has a variable speed limit. Between Merzenich and Elsdorf, there is a speed limit of 130 km/h, that has been imposed in 2017, due to an increase of accidents. Between Kreuz Köln-West and Kreuz Heumar the speed limit is 120 km/h. From Kreuz Köln-Ost to Refrath there is a maximum limit of 100 km/h. The westbound section between Köln-Merheim and Kreuz Köln-Ost is restricted to 80 km/h. The section between Refrath and the current terminus at Krombach has no speed limit. Only between Untereschbach and Refrath westbound there is a 100 km/h speed limit from 6 - 10 am on weekdays. It is mostly 2 lanes each way, but between Untereschbach and Wiehl there are several additional climbing lanes in both directions. The eastern part starts at the Kirchheim intersection (with the A 7) and goes through Eisenach, Gotha, Erfurt, Weimar, Jena, Gera, Chemnitz and Dresden to Görlitz, where it crosses the border to Poland and continues as A4 (Poland). The westernmost 11 kilometers of the A 4 form the most easterly stretch of the European route E314: continuing east from the Aachen interchange (Kreuz Aachen), the A 4 is part of the European route E40. European routes don't have gaps and E40 follows A 45 and A 5, which is a suitable route past the gap of A 4. The first sections of the A 4 were built in the years 1934 to 1937. Because it crossed the border between East and West Germany several times, those parts were closed and fell into decay during the time of German division. Repairs of those parts are scheduled to be completed in 2007. Reconstruction of last section in Thuringia between Eisenach and Gotha near the former Inner German Border began in 2007 and required building 25 km (16 mi) of new road. Vinci SA and Hochtief were the contracted to build the new road.

Bundesautobahn 61 (translates from German as Federal Motorway 61, short form Autobahn 61, abbreviated as BAB 61 or A 61) is an autobahn in Germany that connects the border to the Netherlands near Venlo in the northwest to the interchange with A 6 near Hockenheim. In 1965, this required a redesign of the Hockenheimring. The autobahn runs parallel to the A 3 on the opposite side of the Rhine. Between Mönchengladbach and Bergheim in the north and Worms, Ludwigshafen and Speyer in the south, it cuts through the landscapes of Eifel and Hunsrück, avoiding areas of dense population while still in proximity to Cologne, Bonn, Koblenz and Bingen. The A 61, built in the 1970s, is the most western connection from the Netherlands and Belgium to southern Germany so many trucks and tourists from these countries frequent the A 61. Between Kreuz Mönchengladbach and Wanlo, the speed limit is 120 km/h. The section between the junctions Wanlo and Jackerath was upgraded to three lanes in 2005. The speed limit there is 130 km/h, paid for by RWE Power that in return received permission to close a section of A 44 for their Garzweiler surface mining operation. By 2017, the A 44 will be restored and the Wanlo-Jackerath-section of the A 61 will be closed instead. Between Dreieck Erfttal and Kreuz Bliesheim the A 1 and A 61 run concurrently. The motorway has three lanes each way and a variable speed limit here. Since 4 April 2012, the A 61 continues into the Netherlands as A74. This short motorway connects the A 61 at the border with the Dutch A 73. Previously, all traffic had to go through the city of Venlo. Part of the A61 motorway near the village of Gelsdorf had been designed for use as a runway to service travel to the nearby Government bunker facility and in an emergency a section would have been dedicated for use as an airport with spacious aircraft parking spaces at both ends disguised as roadside car parks.

Originally ending near the city of Delmenhorst, an extension connecting the A 28 to the A 1 has been finished in 2009.

Bundesautobahn 9 (translates from German as Federal Motorway 9, short form Autobahn 9, abbreviated as BAB 9 or A 9) is an autobahn in Germany, connecting Berlin and Munich via Leipzig and Nuremberg. It is the fifth longest autobahn spanning 529 km (328.71 mi).

Bundesautobahn 620 (translates from German as Federal Motorway 620, short form Autobahn 620, abbreviated as BAB 620 or A 620) is an autobahn in Germany, connecting Saarlouis with Saarbrücken. Together with the BAB8, it serves as part of the connection between Luxembourg and Germany. As the major part of the BAB 620 is alongside the river Saar, one section in Saarbrücken, the so-called "Stadtautobahn" is subject to flooding several times a year. As a joke, locals call it "Bundesschifffahrtsstrasse" (Federal water lane) and "Nebenfluss der Saar mit 13 Buchstaben" (tributary of the Saar with 13 letters) because of that. A tunnel is being discussed to circumvent that problem.

Bundesautobahn 544

Bundesautobahn 27 (translates from German as Federal Motorway 27, short form Autobahn 27, abbreviated as BAB 27 or A 27) branches off the A 7 at Autobahndreieck Walsrode to the northwest, crossing A 1 at the Bremer Kreuz and continuing eastwards of Bremen, toward Cuxhaven. Due to the large ports (especially in Bremerhaven) alongside the Autobahn, there is a lot of heavy truck traffic present. Its northernmost part, between Bremen and Cuxhaven, largely replaced the Bundesstraße 6, although some maps still show the B 6 within the city limits of Bremerhaven.

Bundesautobahn 39 (translates from German as Federal Motorway 39, short form Autobahn 39, abbreviated as BAB 39 or A 39) is an autobahn in northern Germany. It currently connects the cities of Salzgitter, Braunschweig and Wolfsburg, with a planned extension to Lüneburg. The A 39 begins north of Wolfsburg and ends at the A 7 close to Salzgitter. It crosses the A 2 south of Wolfsburg close to Königslutter.

Bundesautobahn 860

Bundesautobahn 20 (translates from German as Federal Motorway 20, short form Autobahn 20, abbreviated as BAB 20 or A 20) is an autobahn in Germany. It is colloquially known as Ostseeautobahn ("Baltic Freeway") or Küstenautobahn ("Coastal Freeway") due to its geographic location near the Baltic Sea coastline. The road is not built along a straight line, instead it is built near important cities (Wismar, Rostock, Stralsund), to make it more beneficial for travel between these cities, and also to serve as bypass. Construction started in 1992, only two years after the German reunification, near the junction Wismar-Nord and was completed in December 2005, when the last section was opened near Tribsees by Chancellor Angela Merkel. Building costs are estimated at € 1.8 billion.279 km of the autobahn are in Mecklenburg-Vorpommern, 27 km in Brandenburg and 30 km in Schleswig-Holstein, making the A 20 the longest continuously built new autobahn since 1945. On July 28, 2009, the western extension started with the opening between Autobahnkreuz Lübeck and junction Geschendorf. In the meantime the next six kilometers to the temporary end at Weede has been opened for traffic. The extension and opening of the section between the temporary end in Weede and Autobahnkreuz Bad Segeberg is planned for the end of 2010. Further extension west is planned and awaiting funding, including a tunnel under the Elbe and a 2-way connection with the also-planned A 26. North of Hamburg the A 20 will have a unique function, namely the connection of the highways A 1, A 21, A 7 and A 23, but it will also function as a northern bypass of the city-region of Hamburg which will take traffic going from France and the Benelux countries to Denmark and Sweden away from Hamburg.

Bundesautobahn 4

Bundesautobahn 71 (translates from German as Federal Motorway 71, short form Autobahn 71, abbreviated as BAB 71 or A 71) is an Autobahn in Germany. It connects the A 38 and Erfurt to the A 70 near Schweinfurt. A further northern extension to the A 14 near Plötzkau has been proposed by the state government of Sachsen-Anhalt. Construction on the A 71, supervised by DEGES, began in 1996, most parts were being opened by December 2005. The project was completed in September 2015. The section through the Thuringian Forest was the most expensive road ever built in Germany with an average cost of €10 million per kilometre (€16,000,000/mi). This section includes the Rennsteig Tunnel which is the longest road tunnel in Germany at 8 km (5.0 mi) and is called "Thüringer wald Autobahn" (Thuringian Forest Motorway).

Bundesautobahn 62 (translates from German as Federal Motorway 62, short form Autobahn 62, abbreviated as BAB 62 or A 62) is an autobahn in southwestern Germany, connecting the A 1 with the A 6. It also connects numerous communities throughout the central Hunsrück. The highway was constructed in the early or mid-1980s.

Bundesautobahn 210 (translates from German as Federal Motorway 210, short form Autobahn 210, abbreviated as BAB 210 or A 210) is a route that connects the federal state capital of Kiel to Rendsburg. This route serves to further ease the ground transportation route from Kiel to Schleswig and into Scandinavia.

Bundesautobahn 31

Bundesautobahn 215 (translates from German as Federal Motorway 215, short form Autobahn 215, abbreviated as BAB 215 or A 215) is an autobahn that connects the federal state capital of Kiel to Hamburg via Autobahn 7. This route serves to further ease the ground transportation route from Kiel to the rest of Holstein and into central Europe.

Bundesautobahn 352 (translates from German as Federal Motorway 352, short form Autobahn 352, abbreviated as BAB 352 or A 352) is an autobahn spur north of Hanover in northwestern Germany. It is an important bypass for traffic from the A 7 to the A 2, avoiding the Hannover-Ost ("East") interchange between the two autobahns. Hannover Airport is also situated near the A 352, which is why locals occasionally refer to it as the Flughafenautobahn ("airport autobahn").

Bundesautobahn 293

Bundesautobahn 683 (translates from German as Federal Motorway 683, short form Autobahn 683, abbreviated as BAB 683 or A 683) was a motorway in Germany, in the state of Hesse. It was constructed from 1974 to 1979 and led south from the Hanau exit of the A 3. It went through Rodgau and ended at Dieburg, where the Autobahn connected to the leading westward to Darmstadt. The Autobahn was downgraded to a Bundesstraße (Bundesstraße 45) in the 80s. Only the signs were changed though - the road, equipped with parking fields and hard shoulders, remained the same. In the 90s the road was continued northward, which turned the Hanau exit into a true interchange and removed the roundabout that used to be there. The continuation to the north, leading through the city of Hanau, is now called the .

Bundesautobahn 37 (translates from German as Federal Motorway 37, short form Autobahn 37, abbreviated as BAB 37 or A 37) is an autobahn in the Region Hannover, Germany. It consists of two parts, one connecting the borough of Hannover-Buchholz to Burgdorf via , the other connecting the Hanover fairground to the A 7. The two parts are linked by the B 3, the whole system is known as the Messeschnellweg (fairground expressway). During large fairs, for example CeBIT or Hannover Messe, the Messeschnellweg can be transformed to a four-lane one way road on the fly to allow for quicker travel to and from the fairground.

Bundesautobahn 252 (translates from German as Federal Motorway 252, short form Autobahn 252, abbreviated as BAB 252 or A 252) is a planned short motorway in Hamburg in northern Germany. The A 252 is called Hafenquerspange (port link road) and planned to connect the A 1 and A 7. It is planned to be finished in 2013.

Bundesautobahn 555 (translates from German as Federal Motorway 555, short form Autobahn 555, abbreviated as BAB 555 or A 555) is an autobahn connecting the cities of Cologne and Bonn. It was constructed between 1929 and 1932, and opened to traffic on August 6, 1932. Because it was the first public road that was limited to motorized vehicles and had no level crossings, it is commonly regarded as the oldest German Autobahn, even though it was only a country road at first and wasn't officially awarded Autobahn status until 1958. Until it was extended to six lanes between 1964 and 1966, there was no central barrier. Except for deceleration at each end, the A 555 did not have a speed limit, resulting in about 15 km of mostly straight three-lane-road on flat terrain, enabling motorists to drive their vehicles at top speed. Especially at night, speeds in excess of 200 km/h were not unusual. In 2004, however, a speed limit was introduced around Wesseling for reasons of noise reduction, effectively cutting the area for legal speeding in half. In Cologne, the A 555 spur has the by-name "Diplomatenrennbahn" (Diplomat race track), seemingly because foreign diplomats and state visitors liked to take a spin from Bonn to Cologne and back when Bonn still was the capital of the Federal Republic of Germany. Bonn locals, however, use that term for the B 9 where diplomats regularly sped under protection of diplomatic immunity.

Bundesautobahn 63 (translates from German as Federal Motorway 63, short form Autobahn 63, abbreviated as BAB 63 or A 63) is an autobahn in southwestern Germany. It connects the Mainz area to Kaiserslautern and the A 6 and is therefore an important connection between the Rhine/Main and the Saar areas. It was constructed during the 1980/90s and finished 2004 (last section Sembach - Kaiserslautern) Historically an uninterrupted Autobahn, one final 10-kilometre (6.2 mi) section was added between Sembach and Kaiserslautern at the current site of the Dreieck Kaiserslautern/KL-Zentrum Ausfahrt. This relieved the heavy traffic on the two lane .

Bundesautobahn 85 (translates from German as Federal Motorway 85, short form Autobahn 85, abbreviated as BAB 85 or A 85) was a planned Autobahn in Germany, supposed to connect Schwäbisch Hall with Ravensburg via Backnang, Stuttgart, Metzingen and Riedlingen. Its construction has been postponed.

Bundesautobahn 37 (translates from German as Federal Motorway 37, short form Autobahn 37, abbreviated as BAB 37 or A 37) is an autobahn in the Region Hannover, Germany. It consists of two parts, one connecting the borough of Hannover-Buchholz to Burgdorf via , the other connecting the Hanover fairground to the A 7. The two parts are linked by the B 3, the whole system is known as the Messeschnellweg (fairground expressway).

Bundesautobahn 66 (translates from German as Federal Motorway 66, short form Autobahn 66, abbreviated as BAB 66 or A 66) is an autobahn in southwestern Germany. It connects the Taunus to Fulda, passing close to Frankfurt am Main. The first part of the autobahn between Wiesbaden and the Nordwestkreuz Frankfurt, was opened as early as 1934, then called the Rhein-Main-Schnellweg. It became an autobahn in 1965. Near Frankfurt-Höchst, the highway is one of the busiest in Germany with an average of more than 130,000 vehicles per day.

Bundesautobahn 4 (translates from German as Federal Motorway 4, short form Autobahn 4, abbreviated as BAB 4 or A 4) is an autobahn that crosses Germany in a west–east direction. The western segment has a length of 156 km (97 mi), the part in the east is 429 km (267 mi) long. Works to continue the A 4 are in progress, but currently no plans exist to fill the gap completely.

Bundesautobahn 37

Bundesautobahn 22 (translates from German as Federal Motorway 22, short form Autobahn 22, abbreviated as BAB 22 or A 22) is an autobahn in Germany that is in the planning stage. The A 22 is supposed to connect the A 28 near Westerstede with the A 27 near Bremerhaven, crossing the A 29 near Jaderberg . A vital part of the projected A 22 is the Wesertunnel south of Bremerhaven, which is currently part of . Eastwards of Bremerhaven, the A 22 planning proposes passing Stade and crossing the Elbe river as part of the A 20.Details of the trajectory are being discussed in the counties and municipalities involved; the projected start of construction is said to be around 2013.

Bundesautobahn 6 (translates from German as Federal Motorway 6, short form Autobahn 6, abbreviated as BAB 6 or A 6), also known as Via Carolina (between Nuremberg and the Czech border continuing to Prague) is a 477 km (296.4 mi) long German autobahn. It starts at the French border near Saarbrücken in the west and ends at the Czech border near Waidhaus in the east. The first plans for the A 6 were laid out in 1935, construction on several parts began in 1938. In 1940, construction near Mannheim was stopped when the bridge across the Rhine collapsed, killing many workers. A new bridge, the Theodor Heuss Bridge (Frankenthal), was opened in 1953. Other parts of the A 6 were completed in 1941. A part near Kaiserslautern was used as an airstrip by the Luftwaffe during World War II. After the war, it was taken over by US forces and became the Ramstein Air Base, while the A 6 was re-built south of the air base. In the 1960s, construction was continued. One new section cut through the Hockenheimring, requiring a major redesign of the race track which resulted in the construction of the Motodrom stadium. Much like its southern counterpart, the A 8, the A 6 is relatively old and has received little upgrading, making it difficult for it to handle today's traffic. The section around Mannheim is currently being widened and modernised from a four-lane to a six-lane motorway requiring the construction of a new bridge over the River Neckar. About the Kocher Viaduct (German: Kochertalbrücke) near Schwäbisch Hall, the Autobahn 6 crosses the Kocher valley between Heilbronn and Nuremberg. With its maximum height of 185 m (607 ft) above the valley bottom, it is the highest viaduct in Germany. The direct motorway connection between Prague and Paris was completed when the last missing section between junction Amberg-Ost and interchange Oberpfälzer Wald was inaugurated on 10 September 2008.

Bundesautobahn 71 (translates from German as Federal Motorway 71, short form Autobahn 71, abbreviated as BAB 71 or A 71) is an Autobahn in Germany. It connects the A 38 and Erfurt to the A 70 near Schweinfurt. A further northern extension to the A 14 near Plötzkau has been proposed by the state government of Sachsen-Anhalt.

Bundesautobahn 14 (translates from German as Federal Motorway 14, short form Autobahn 14, abbreviated as BAB 14 or A 14) is an autobahn in eastern Germany. The route comprises two disconnected sections:
* The old A 241. A North-South route in Mecklenburg-Vorpommern which runs from Wismar to Schwerin.
* The original A 14. A West-East route which starts at the A 2 near Magdeburg in Saxony-Anhalt and terminates at the A 4 at Dresden in Saxony. On the way, it serves Halle and Leipzig. Construction is underway to connect the two sections.

Bundesautobahn 62

Bundesautobahn 388 (translates from German as Federal Motorway 388, short form Autobahn 388, abbreviated as BAB 388 or A 388) was an autobahn spur in Göttingen. It has now been downgraded and made part of the Bundesstraße 27, as the A 38 has recently been finished. The A 388 was supposed to be the first part of the A 38, branching off the A 7 in the North of Göttingen, however plans were carried out differently and the A 38 now meets with the A 7 near Friedland.

Bundesautobahn 24 (translates from German as Federal Motorway 24, short form Autobahn 24, abbreviated as BAB 24 or A 24) is an autobahn in northern Germany that connects the large metropolitan regions of Hamburg and Berlin. It was one of the three transit access roads to West Berlin during the Cold War. On that road, there is a 150 km (93 mi) long section that has no speed limit at all (only a recommended speed of 130 km/h), which means that about 65% of that Autobahn can be driven at very high speed.

Bundesautobahn 65 (translates from German as Federal Motorway 65, short form Autobahn 65, abbreviated as BAB 65 or A 65) is an autobahn in southwestern Germany. The newest section, between Neustadt and Landau, was opened only in the early 1990s. Plans to build a final stretch between Kandel or Wörth am Rhein and the French autoroute towards Haguenau and Strasbourg were not implemented during the 1990s when the focus of Autobahn construction switched to the eastern side of the country: the project remains contentious because of the ecological impact it could have on the Bienwald (wooded area) through which the road would run.

Bundesautobahn 45 (translates from German as Federal Motorway 45, short form Autobahn 45, abbreviated as BAB 45 or A 45) is an autobahn in Germany, connecting Dortmund in the west with Aschaffenburg in the southwest. It is colloquially known as the Sauerlandlinie (Sauerland line) as it runs through the hilly, rural Sauerland region between Hagen and Siegen. The A45 has a large number of bridges to cross valleys, the highest of which is the Sichter Valley bridge (Talbrücke Sichter) between Lüdenscheid and Meinerzhagen at 530 metres above mean sea level. It is mostly two lanes each way with frequent climbing lanes between Dortmund-Hafen and the Gambacher Kreuz intersection. In March 2013 30 people were injured in a pile-up on the A45.

Bundesautobahn 861 (translates from German as Federal Motorway 861, short form Autobahn 861, abbreviated as BAB 861 or A 861) is an autobahn in Germany. The A 861 opened on March 7, 2006. Its northern terminus with the A 98 is merely a ninety-degree turn accompanied by a designation change. The A 98 will not be completed east of this interchange until 2013. At the southern end of the A 861 is the Rheinfelden border crossing with Switzerland. A small portion of motorway connects this crossing to Switzerland's A 3 at junction 14. Vehicles on this small section of motorway do not need the vignette that is normally required to travel on Swiss motorways. This is to allow German traffic and Swiss traffic that do not have vignettes to cross between the Swiss and German halves of Rheinfelden without having to buy one. A vignette is required to go past the junction Rheinfelden-West, as traffic then must enter the A 3. The European route E54 is concurrent with the A 861 until junction 2.

It is a short branch of the A 1 north of Lübeck, sometimes called "Nordtangente Lübeck" ("Lübeck northern tangente"). It connects the A 1 with the Bundesstraße 75, which goes to the Lübeck borough of Travemünde.

Bundesautobahn 43 (translates from German as Federal Motorway 43, short form Autobahn 43, abbreviated as BAB 43 or A 43) is an autobahn in western Germany, connecting Münster via Recklinghausen to Wuppertal. It is an important bypass for traffic coming from the A 1 wanting to go to the western Ruhr valley and wanting to avoid tailbacks at the Kamener Kreuz near Dortmund.

Bundesautobahn 19 (translates from German as Federal Motorway 19, short form Autobahn 19, abbreviated as BAB 19 or A 19) is an autobahn in eastern Germany that connects the Baltic port of Rostock to the A 24, which continues to the A 10 ring road around Berlin. The Warnowtunnel is the only stretch of autobahn so far that requires the payment of a general road toll for all vehicles.

Bundesautobahn 862 (translates from German as Federal Motorway 862, short form Autobahn 862, abbreviated as BAB 862 or A 862) was an autobahn in Germany. Its purpose was to connect the French Autoroute 36 with the German Bundesautobahn 5 via a bridge over the Rhine. At 400 metres, the A 862 was Germany's shortest autobahn; it was later integrated as an onramp into the A 5.

Bundesautobahn 5 (translates from German as Federal Motorway 5, short form Autobahn 5, abbreviated as BAB 5 or A 5) is a 445 km (277 mi) long Autobahn in Germany. Its northern end is the Hattenbach triangle intersection (with the A 7. The southern end is at the Swiss border near Basel. It runs through the German states of Hessen and Baden-Württemberg and connects on its southern ending to the Swiss A 2.

Bundesautobahn 13 (translates from German as Federal Motorway 13, short form Autobahn 13, abbreviated as BAB 13 or A 13) is an autobahn in eastern Germany, connecting Berlin with Dresden.

Bundesautobahn 571 (translates from German as Federal Motorway 571, short form Autobahn 571, abbreviated as BAB 571 or A 571) is an autobahn in Germany. The A 571 is one of the shortest autobahns in Germany, measuring 2.4 km. The autobahn is located entirely in a rural area east of Bad Neuenahr-Ahrweiler. The A 571's southern end is located at the three-way interchange Sinzig with the A 61. The original plan of the A 571 was to link a much longer A 31, which was to end in Bad Neuenahr-Ahrweiler, at the A 61. However, the A 31 was cancelled south of Mülheim an der Ruhr due to community opposition, but not before a few vestiges of the project were left behind. The A 571's northern end is merely a ninety-degree curve back to the west, after which the road becomes a branch of the , which continues into Bad Neuenahr-Ahrweiler as a grade-separated Kraftfahrstraße (expressway). The other vestiges are the easternmost section of the A 560 and all of the A 573.This was to be the location of a three-way interchange with the cancelled A 31. Construction began in March 2009 on a project to extend the B 266 expressway across Bad Neuenahr-Ahrweiler and connect the A 571 to the A 573. The current northern terminus of the A 571 will become a three-way interchange with an upgraded B 266, according to current plans. Construction is estimated to finish by 2015.

Bundesautobahn 250 (translates from German as Federal Motorway 250, short form Autobahn 250, abbreviated as BAB 250 or A 250) was an autobahn in north Germany, which was colloquially referred to as the Maschener Autobahn ("Maschen Motorway"). It began near Hamburg and ran in an easterly direction for 28 kilometres to Lüneburg, where it became the B 4 and later the B 209. The motorway had two lanes throughout and was opened in four sections:1985: AK Maschen – AS Maschen1987: AS Maschen – AS Winsen (Luhe)-West1991: AS Winsen (Luhe)-West – AS Winsen (Luhe)-Ost1995: AS Winsen (Luhe)-Ost – Lüneburg-Nord When the planned junction from the A 250 to the A 39 from Wolfsburg is built there will be a motorway straight through from the industrial region of Brunswick and Salzgitter to the Hamburg ports. The motorway was completed in 2010 and the A 250 became part of the A 39.

Bundesautobahn 20 (translates from German as Federal Motorway 20, short form Autobahn 20, abbreviated as BAB 20 or A 20) is an autobahn in Germany. It is colloquially known as Ostseeautobahn ("Baltic Freeway") or Küstenautobahn ("Coastal Freeway") due to its geographic location near the Baltic Sea coastline. The road is not built along a straight line, instead it is built near important cities (Wismar, Rostock, Stralsund), to make it more beneficial for travel between these cities, and also to serve as bypass.

Bundesautobahn 395 (translates from German as Federal Motorway 395, short form Autobahn 395, abbreviated as BAB 395 or A 395) was an autobahn in Germany. It has been redesignated as a part of the A 36 as of January 1, 2019. The A 395 began at an interchange with the A 39 and B 248 south of Brunswick (Braunschweig). From there, the road headed in a general southerly direction, bypassing Wolfenbüttel, Schladen and other, smaller towns. The southern end of the A 395 came in the town of Vienenburg, at a trumpet interchange with a freeway portion of the B 6/B 6n. The B 6 continues to the south and west towards Goslar and the B 4, while the B 6n continues east towards Leipzig, eventually meeting with the A 14. The A 395 was the longest three-digit autobahn in Germany, although it was formerly 7 km longer. In 2001, the section of autobahn from Bad Harzburg to Schlewecke became the northernmost part of the B 4, while the section of freeway from that point to the current southern terminus was returned to the B 6. It was designated as A 369 in 2019. The northernmost 400 m of the A 395, between the junctions Braunschweig-Melverode and Braunschweig-Süd, was not considered to be part of the autobahn system. There is an at-grade entrance and exit from a large car dealership and gas station along the southbound side of the road just before Braunschweig-Melverode. Therefore, the A 395 was officially considered to start immediately after that junction, and thus also had no connection to the remaining autobahn network.

Bundesautobahn 485 (translates from German as Federal Motorway 485, short form Autobahn 485, abbreviated as BAB 485 or A 485) is an autobahn in Germany. The A 485 is an eastern bypass of the town of Gießen. Between junctions 1 and 7, it is the eastern leg of the Gießener Ring. The A 485 is one of two completed portions of an abandoned plan to extend the A 49 to Darmstadt. The other portion is the A 661 from junction 8 onwards. Junction 1 is split into three parts. Heading northbound, the first part that is encountered is a trumpet interchange with the B 3a freeway. The B 3a continues northbound, while A 485 traffic is required to exit the freeway to the right. After exiting, the A 485 continues on a shorter stretch of freeway, passing the Marburger Straße junction before ending at a trumpet with the A 480. All three parts are signed as junction 1, and both trumpets are named Gießener Nordkreuz.

Bundesautobahn 648 (translates from German as Federal Motorway 648, short form Autobahn 648, abbreviated as BAB 648 or A 648) is a very short Autobahn and connects the western part of Frankfurt am Main with the Alleenring. The A 648 is the most important way to the city and to the Frankfurt Trade Fair.

Bundesautobahn 65 (translates from German as Federal Motorway 65, short form Autobahn 65, abbreviated as BAB 65 or A 65) is an autobahn in southwestern Germany. The newest section, between Neustadt and Landau, was opened only in the early 1990s.

Bundesautobahn 623 (translates from German as Federal Motorway 623, short form Autobahn 623, abbreviated as BAB 623 or A 623) is an autobahn in Germany. The A 623 is a spur connecting the A 8 to Saarbrücken. As with the A 1 to the west, the A 623 does not enter the inner city. Connections to arteries into Saarbrücken are made at the final two junctions. Junction 7 offers a connection to the Camphauser Straße expressway, which leads to the and the B 51. The road also continues past junction 8 into Saarbrücken, but as the . The section of B 41 immediately after junction 8, about 1.2 km, is a short Kraftfahrstrasse (expressway). The entirety of the A 623 was once part of the B 41. When the road was designated as an autobahn, the B 41 designation remained. The concurrency is indicated on all distance signs along the A 623, a rarity for German roads. The concurrency continues a further three junctions to the east along the A 8. There is no junction 6 along the A 623. This was to be the connection point with a proposed alignment of the A 1 into Saarbrücken. The planned route of the A 1 would have diverged from a location near that road's present-day junction 148 (Saarbrücken-Von der Heydt), then connecting with the A 623, continuing down the Camphauser Straße expressway, through Saarbrücken, and across the Westspange bridge to end at the A 620. For the same reason, the A 1 has no junction 149.

Bundesautobahn 524 (translates from German as Federal Motorway 524, short form Autobahn 524, abbreviated as BAB 524 or A 524) is an autobahn in Germany. The A 524 is a short connector, heading west from Breitscheid and the A 52 towards Krefeld. The autobahn was built in the 1980s by upgrading the . A short (1 km) section of freeway from the A 57 into Krefeld is also designated as part of the A 524. Currently, an extension westward to the A 59 is listed as "high priority" in the latest Bundesverkehrswegeplan (Federal Transport Infrastructure Plan), and has started construction with completion slated for 2013. This project will be accompanied by a new free-flowing 4-way interchange to replace two low-capacity junctions: a T-intersection with the A 59 and a half-folded-diamond interchange with the B 8. Completion of the interchange is also set for 2013, with the older junctions expected to be closed at the same time. Further extension along the B 288, across the Rhine and into Krefeld, is not listed in the Bundesverkehrswegeplan as being necessary at the present time. Rather, it is considered something that will only become important in the future. Therefore, it is only in planning, with construction beginning in 2016 at the earliest.

Bundesautobahn 485 (translates from German as Federal Motorway 485, short form Autobahn 485, abbreviated as BAB 485 or A 485) is an autobahn in Germany. The A 485 is an eastern bypass of the town of Gießen. Between junctions 1 and 7, it is the eastern leg of the Gießener Ring. The A 485 is one of two completed portions of an abandoned plan to extend the A 49 to Darmstadt. The other portion is the A 661 from junction 8 onwards.

Bundesautobahn 114 (translates from German as Federal Motorway 114, short form Autobahn 114, abbreviated as BAB 114 or A 114) is a motorway in the north of the German capital Berlin. It connects the A 10 (Berliner Ring) starting at the Autobahndreieck Pankow over a seven kilometers distance to the main center of Berlin. The motorway was released for traffic between 1973 and 1982.

Bundesautobahn 2 (translates from German as Federal Motorway 2, short form Autobahn 2, abbreviated as BAB 2 or A 2) is an autobahn in Germany that connects the Ruhr area in the west to Berlin in the east. The A 2 starts at the junction with the A3 near the western city of Oberhausen, passes through the north of the Ruhr valley, through the Münsterland and into Ostwestfalen, crossing the former inner German border and continuing through the Magdeburger Börde to merge into the Berliner Ring shortly before reaching Berlin. Major cities such as Magdeburg, Braunschweig, Hannover and Dortmund are situated very close to the A 2. The A 2 is one of the most important autobahns, connecting several large industrial areas with each other.

Bundesautobahn 61 (translates from German as Federal Motorway 61, short form Autobahn 61, abbreviated as BAB 61 or A 61) is an autobahn in Germany that connects the border to the Netherlands near Venlo in the northwest to the interchange with A 6 near Hockenheim. In 1965, this required a redesign of the Hockenheimring. The A 61, built in the 1970s, is the most western connection from the Netherlands and Belgium to southern Germany so many trucks and tourists from these countries frequent the A 61. Between Kreuz Mönchengladbach and Wanlo, the speed limit is 120 km/h.

Bundesautobahn 540 (translates from German as Federal Motorway 540, short form Autobahn 540, abbreviated as BAB 540 or A 540) is an autobahn in western Germany, connecting Jüchen and Grevenbroich, partly replacing the . It is two lanes in each direction. There is no speed limit and very little traffic on this autobahn. From 1999 to 2005 this road have been used as afilming location for RTL Television series Alarm für Cobra 11 – Die Autobahnpolizei.

Bundesautobahn 661 (translates from German as Federal Motorway 661, short form Autobahn 661, abbreviated as BAB 661 or A 661) - also called Osttangente Frankfurt (easttangent Frankfurt) or Taunusschnellweg - is a 40 km (25 mi) long Autobahn in Germany. It starts in Oberursel and goes along Bad Homburg, Frankfurt am Main, Offenbach am Main and Neu-Isenburg until it is ending in Egelsbach. The today's A 661 were opened with section Bad Homburg (today junction 3) and Frankfurt-Bonames (formerly junction 5b). While continuation to Oberursel-Nord happens easy the construction to Frankfurt-Eckenheim get delayed very much. There was an interims end between Bonames and Eschersheim near the Bonameser Platz. After many years the extension to the Friedberger Landstraße follows. The section between Offenbach and Egelsbach was also already constructed, but at this time as a part of the A 49 which was planned as an Autobahn between Kassel and Darmstadt. After this plan had been stopped this section becomes a part of the A 661. The section between the two others had been finalized step-by-step and was closed in 1995. At the newest section between the Friedberger Landstraße and Frankfurt-Ost (close to the Eissporthalle the lanes are very tight because of economy measures. There is no hard shoulder at the moment and the lanes are only separated by a one meter high concrete wall. From the planned section only the half had been built until 1995 because of the bridge which is needed at the Bornheimer Hang, so the lanes in both directions are smaller in this section than in the others. When the section is completed it is planned that there are three lanes like in the other sections and to build two more bridges. One bridge over the Seckbacher Tal (270 m) and one over the Erlenbruch (200 m). The construction has started in November 2007 and the plan is that the work is completed in 2009. By completing the A 661 also the bridges which are needed for the Autobahndreieck Erlenbruch (one double-deck bridge and the ramps). Between Seckbach and Bornheim is a special construction. The "Galerie Seckbacher Straße" which was built in 1995 has two functions. At first is a bridge over the Autobahn for the Seckbacher Landstraße and the Heinz-Herbert-Karry-Straße and second it is noise protection for the Seckbach district next to the Autobahn. On the top of the tunnel there was built a small park. In the construction it is possible to connect it to the Alleentunnel of the A 66. At the end near Egelsbach in the south it is also possible to expand the Autobahn. The drive-up and drive-downs to Darmstadt already had been asphalted but the plan to build the Autobahn to Darmstadt was stopped in 1980. At the northern end near Bad Homburg, the Autobahn is made to the Bundestraße 455, and this goes along Kronberg and Königsstein, while the Autobahn has ended there for over 20 years. There were problems with the roadbed on 15 July 2007 because of the heat wave. Some concrete slabs moved over others at A 661 near Dreieich (district Offenbach). The expansion joints were not large enough to fit the concrete slabs when they expanded because of the heat, the police said. Several cars were damaged. The point at the junction in direction Oberursel had to be closed and the cars had to take a parallel lane which was normally used for the other direction.

Bundesautobahn 48 (translates from German as Federal Motorway 48, short form Autobahn 48, abbreviated as BAB 48 or A 48) is an autobahn in western Germany. From the junction with the A 1 it connects to the A 3 and A 61 near Koblenz and is fully part of European route E 44.

Bundesautobahn 261

Bundesautobahn 565 (translates from German as Federal Motorway 565, short form Autobahn 565, abbreviated as BAB 565 or A 565) is an autobahn in Germany, linking the A 59 to the A 61. The oldest section of the A 565 was built in 1959, a branch of the Cologne - Bonn road. This short autobahn, which served as bypass of Bonn, ran from the present-day location of the interchange Bonn-Nord, over the Tausendfüßler bridge, and ending at the current junction Bonn-Endenich. This section was built with two lanes in each direction and was never widened, making it one of the busiest stretches of autobahn in Germany. Later, the road was extended to Lengsdorf, the present-day site of the junction Bonn-Lengsdorf. In 1967, the highway was further extended to the north, across the Rhine and up to the A 170 Flughafenautobahn (present-day A 59). At this point, various sections of the Bonn bypass was signed as the , the B 9n, and the from there to Lengsdorf. Next, work focused on the southern end of the road. The section from Lengsdorf to Meckenheim-Nord was opened in 1971. The road was designated entirely as the A 221 along with the opening of that section. The southernmost portion, from the A 61 to the end of the autobahn, opened in 1973; the remaining portion from the A 61 to Meckenheim-Nord opened two years later. In between the two openings, in 1974, the autobahn received the designation of A 565.

Bundesautobahn 57 (translates from German as Federal Motorway 57, short form Autobahn 57, abbreviated as BAB 57 or A 57) is a German Autobahn that begins at the Dutch-German border near Goch and ends in Köln. It runs parallel to the Rhine River. Neuss and Krefeld are the biggest cities at this motorway. The A 57 is continuation of the Dutch A77. Because of its high economic importance, its nickname is "Trans-Niederrhein-Magistrale". Most of it is two lanes each way only and prone to traffic jams in the rush hour. Currently the sections junction 15 - 18, 19 - 24 and 29 - 30 have three lanes each way. The section from junction 28 to 29 southbound has the possibility to open the hard shoulder as a third lane in heavy traffic. Traffic jams are possible between junctions 10 and 15, 17 and 20 as

Bundesautobahn 52 (translates from German as Federal Motorway 52, short form Autobahn 52, abbreviated as BAB 52 or A 52) is an autobahn in western Germany. It starts at the Dutch-German border near the community of Niederkrüchten, district of Viersen. From Elmpt it runs northeast. Its westernmost part serves as an important commuter route into Düsseldorf. The autobahn becomes Bundesstraße 7 shortly before the , which leads into the Düsseldorf city centre. Traffic of the A 52 is routed through the Düsseldorf city centre on the B 8 and B 1 secondary roads up to Düsseldorf-Mörsenbroich, where the A 52 becomes a road of its own again. The autobahn has three parts: 1.
* Dutch-German border - Niederkrüchten-Elmpt - Mönchengladbach - Düsseldorf-Heerdt 2.
* Düsseldorf-Mörsenbroich - Dreieck Essen-Ost 3.
* Gladbeck - Gelsenkirchen - Marl-Nord A new connection from the Dutch border to Elmpt opened in May 2009. An extension connecting the interchange Essen-Ost with the interchange Gladbeck has been proposed for several years, but has not been built yet, due to the need for several kilometers of tunnels below densely populated areas.

Bundesautobahn 683 (translates from German as Federal Motorway 683, short form Autobahn 683, abbreviated as BAB 683 or A 683) was a motorway in Germany, in the state of Hesse. It was constructed from 1974 to 1979 and led south from the Hanau exit of the A 3. It went through Rodgau and ended at Dieburg, where the Autobahn connected to the leading westward to Darmstadt.

Bundesautobahn 565 (translates from German as Federal Motorway 565, short form Autobahn 565, abbreviated as BAB 565 or A 565) is an autobahn in Germany, linking the A 59 to the A 61.

Bundesautobahn 66 (translates from German as Federal Motorway 66, short form Autobahn 66, abbreviated as BAB 66 or A 66) is an autobahn in southwestern Germany. It connects the Taunus to Fulda, passing close to Frankfurt am Main. The first part of the autobahn between Wiesbaden and the Nordwestkreuz Frankfurt, was opened as early as 1934, then called the Rhein-Main-Schnellweg. It became an autobahn in 1965. The autobahn is incomplete; there still is a gap within Frankfurt city limits. A tunnel was proposed as a solution; however, this has not been implemented because of the high cost of construction. A new section of roadway to close a second gap southwest of Fulda was opened to traffic on 13 September 2014. The section includes a 1.6-kilometre (1.0 mi) cut-and-cover tunnel and replaces a diversion which saw traffic routed onto the B 40 for approximately 9 kilometers before rejoining the A 66 just prior to the junction with the A 7; the new segment cost 154 million euros. A portion of the Kinzig Valley Railway line was also rerouted along the new autobahn segment, which required an additional 60 million euros. Near Frankfurt-Höchst, the highway is one of the busiest in Germany with an average of more than 130,000 vehicles per day.

The section from junction 28 to 29 southbound has the possibility to open the hard shoulder as a third lane in heavy traffic. Traffic jams are possible between junctions 10 and 15, 17 and 20 as well as around junctions 27/28. There is a variable speed limit between junction 10 and 23. The sections from junction 23 to 24 and 27 to 30 have a limit of 100 km/h. Between junctions 27 and 28 the limit was reduced to 80 km/h between 10pm and 6am at night.

Bundesautobahn 81 (translates from German as Federal Motorway 81, short form Autobahn 81, abbreviated as BAB 81 or A 81) is a motorway in Germany. It branches off the A 3 at the Würzburg-West triangle and ends near the border with Switzerland. Further south, the terrain required some spectacular engineering, including a 900-metre-long (3,000 ft) bridge near Horb that spans 125 m above the Neckar river. Currently, the A 81 ends near Singen.

Bundesautobahn 671

Bundesautobahn 555 (translates from German as Federal Motorway 555, short form Autobahn 555, abbreviated as BAB 555 or A 555) is an autobahn connecting the cities of Cologne and Bonn. It was constructed between 1929 and 1932, and opened to traffic on August 6, 1932.

Bundesautobahn 516 (translates from German as Federal Motorway 516, short form Autobahn 516, abbreviated as BAB 516 or A 516) is an autobahn in Germany. The A 516 branches off the A 3 towards the center of Oberhausen. The northern terminus of the A 516 is also the western terminus of the A 2. After a 5 km journey, the autobahn is downgraded to the just after the junction Oberhausen-Eisenheim, 500 m short of the A 42. This is because the junction with the A 42 is not designed as a free-flowing autobahn-to-autobahn junction; rather, it is essentially a diamond interchange with one folded ramp. The speed limit for the entirety of the A 516 is 100 km/h. The limit is reduced to 80 km/h nightly between 22:00 and 6:00. Traffic heading to CentrO on the weekends and around the holiday season regularly creates backups of up to 2 km.

Bundesautobahn 270 (translates from German as Federal Motorway 270, short form Autobahn 270, abbreviated as BAB 270 or A 270) is an autobahn in Germany. The A 270 was created in 2001 as a redesignation of the freeway into the northern part of Bremen. Previously, the freeway was known as the B 74n Lesumerschnellweg. The freeway replaced the route of the through the populated areas of northern Bremen. Recent plans called for an extension of the A 270 around the northern and eastern boundaries of Farge, to end across the street from the terminal of the Farge - Berne ferry. This project was opened to traffic on December 9, 2009. However, it was a built as an at-grade expressway instead, thus requiring the return of the B 74n designation. Because it cuts through a densely developed area, the A 270 is below normal autobahn standards for most of its route. The speed limit for the entire route is 80 km/h (50 mph), and in many places there is no hard shoulder. The A 270 ends just before the A 27/E 234, a short distance after crossing into Lower Saxony. The connection with the A 27 is made at an at-grade intersection. As is expected for urban freeways, some of the junctions are only accessible from one direction; one junction (3b, Lobbendorf) does not permit autobahn traffic to exit at all.

It starts in Oberursel and goes along Bad Homburg, Frankfurt am Main, Offenbach am Main and Neu-Isenburg until it is ending in Egelsbach. The section between the two others had been finalized step-by-step and was closed in 1995.

Bundesautobahn 81 (translates from German as Federal Motorway 81, short form Autobahn 81, abbreviated as BAB 81 or A 81) is a motorway in Germany. It branches off the A 3 at the Würzburg-West triangle and ends near the border with Switzerland. The oldest part of the A 81 between the Weinsberg intersection (A 6) near Heilbronn and Dreieck Leonberg (A 8) near Stuttgart was finished in the years 1938 to 1940. This section included the first tunnel built for an autobahn, the 300-metre-long (980 ft) first Engelberg tunnel near Leonberg. When Weinsberg-Leonberg was upgraded to 3+3 lanes in the 1970s, the tunnel with its two lanes each and steep grades (up to 6%) became something of a bottleneck. In 1999 a new 2,530-metre-long (8,300 ft) Engelberg tunnel was opened. Original plans called for the A 81 to be continued northwards skirting the north-west of Würzburg to join up with the A 7, but these plans were later abandoned. Instead, the A 81 shares a part of the A 8 to the Stuttgart intersection and then continues south on a motorway that was built as A 831 to Gärtringen, where it meets the original line again at a partly finished intersection. As a result of this change of plans, Gärtringen became one of the few exits in the German autobahn network that leave to the left. Further south, the terrain required some spectacular engineering, including a 900-metre-long (3,000 ft) bridge near Horb that spans 125 m above the Neckar river. Currently, the A 81 ends near Singen.

Bundesautobahn 2 (translates from German as Federal Motorway 2, short form Autobahn 2, abbreviated as BAB 2 or A 2) is an autobahn in Germany that connects the Ruhr area in the west to Berlin in the east. The A 2 starts at the junction with the A3 near the western city of Oberhausen, passes through the north of the Ruhr valley, through the Münsterland and into Ostwestfalen, crossing the former inner German border and continuing through the Magdeburger Börde to merge into the Berliner Ring shortly before reaching Berlin. Major cities such as Magdeburg, Braunschweig, Hannover and Dortmund are situated very close to the A 2. The A 2 is one of the most important autobahns, connecting several large industrial areas with each other. The A 2 was modified in the late 1990s, and completely rebuilt in the former East Germany. All of the A 2 has 3 travel lanes and a breakdown lane in each direction.

Bundesautobahn 643 (translates from German as Federal Motorway 643, short form Autobahn 643, abbreviated as BAB 643 or A 643) is a 8.4-kilometer (5.2 mi) short autobahn in Germany. The motorway crosses the Rhine River, connecting the cities of Wiesbaden and Mainz, the capital cities of the German states of Hesse and Rhineland-Palatinate, respectively. It is one of two autobahns in Germany that connect two neighboring state capitals in only one exit. However short the A 643 may be, it is a vital link within the Frankfurt Rhine-Main Region, being only one of three routes across the Rhine in the region. It is an important connection between Autobahn 66 on the north bank of the Rhine and A 60 south of Mainz.

Bundesautobahn 250 (translates from German as Federal Motorway 250, short form Autobahn 250, abbreviated as BAB 250 or A 250) was an autobahn in north Germany, which was colloquially referred to as the Maschener Autobahn ("Maschen Motorway"). It began near Hamburg and ran in an easterly direction for 28 kilometres to Lüneburg, where it became the B 4 and later the B 209. The motorway had two lanes throughout and was opened in four sections:1985: AK Maschen – AS Maschen1987: AS Maschen – AS Winsen (Luhe)-West1991: AS Winsen (Luhe)-West – AS Winsen (Luhe)-Ost1995: AS Winsen (Luhe)-Ost – Lüneburg-Nord
