Maryland Route 7 (MD 7) is a collection of state highways in the U.S. state of Maryland. Known for much of their length as Philadelphia Road, there are five disjoint mainline sections of the highway totaling 40.23 miles (64.74 km) that parallel U.S. Route 40 (US 40) in Baltimore, Harford, and Cecil counties in northeastern Maryland. The longest section of MD 7 begins at US 40 just east of the city of Baltimore in Rosedale and extends through eastern Baltimore County and southern Harford County to US 40 in Aberdeen. The next segment of the state highway is a C-shaped route through Havre de Grace. The third mainline section of MD 7 begins in Perryville and ends at US 40 a short distance west of the start of the fourth section, which passes through Charlestown and North East before ending at US 40 just west of Elkton. The fifth segment of the highway begins at South Street and passes through the eastern part of Elkton before reconnecting with US 40 west of the Delaware state line.MD 7 is the old alignment of US 40 in northeastern Maryland. The route was first laid out early in colonial times and later formed part of the post road between Baltimore and Philadelphia and between the northern and southern colonies. The highway in Baltimore and Harford counties became a turnpike in the 19th century. The Maryland State Roads Commission marked portions of what became known as the Philadelphia Road close to Baltimore and between Perryville and Elkton for improvement as state roads in 1909. Those sections and the highway between Aberdeen and Havre de Grace were constructed as modern roads in the early to mid-1910s. The remainder of the highway was constructed in the 1920s and designated US 40 in 1927. The high volume of traffic and the required continuous expansion of the highway led the Maryland State Roads Commission to construct the modern Pulaski Highway between 1935 and 1941. Old sections of US 40 became segments of MD 7 between 1938 and 1941 as portions of the new four-lane divided highway opened from Baltimore to Elkton.

Maryland Route 650 (MD 650) is a state highway in the U.S. state of Maryland. Known as New Hampshire Avenue for most of its length, the state highway runs 25.89 mi (41.67 km) from Eastern Avenue at the Washington, D.C. border north to MD 108 in Etchison. MD 650 serves as a major north-south commuter route in northwestern Prince George's County and eastern Montgomery County, connecting the District of Columbia with the residential suburbs of Takoma Park, Langley Park, Maryland, Adelphi, Hillandale, White Oak, and Colesville. By contrast, the part of MD 650 north of Spencerville is a quiet rural road connecting several small communities along the northeastern fringe of Montgomery County.MD 650 was originally built between Takoma Park and Adelphi in the late 1930s as an extension of New Hampshire Avenue out of Washington. In the 1950s, the state highway was extended north, taking over portions of MD 320 and U.S. Route 29 (US 29) and all of MD 116. Beginning in the 1950s and continuing through the 1990s, MD 650 has been expanded to a multi-lane divided highway in stages from its southern terminus north to Spencerville.

Maryland Route 648 (MD 648) is a collection of state highways in the U.S. state of Maryland. These nine highways are current or former sections of the Baltimore–Annapolis Boulevard between Annapolis and Baltimore via Glen Burnie. There are five signed mainline segments of MD 648 through Arnold, Severna Park, Pasadena, Glen Burnie, Ferndale, and Pumphrey in northern Anne Arundel County; Baltimore Highlands in southern Baltimore County; and the independent city of Baltimore. MD 648 mainly serves local traffic along its meandering route, with long-distance traffic intended to use the parallel and straighter MD 2 south of Glen Burnie and freeway-grade Interstate 97, I-695, and MD 295 between Glen Burnie and Baltimore.The Baltimore–Annapolis Boulevard was constructed in the early to mid-1910s as the primary highway between Baltimore and Annapolis. The highway was specifically authorized by the Maryland General Assembly, which insisted the Maryland State Roads Commission complete the highway along its originally planned route instead of using what is now MD 2 north of Glen Burnie. The boulevard was designated parts of MD 2 and MD 3 in 1927; the latter number was replaced with U.S. Route 301 (US 301) in 1939. MD 648 was assigned to the Baltimore–Annapolis Boulevard south of Glen Burnie in the late 1930s after it was functionally replaced by MD 2's present course. In the late 1950s, after US 301 was moved to freeways from south of Glen Burnie to Baltimore, MD 648 was extended north from Glen Burnie into Baltimore. MD 648 has had few major changes since then, the most significant being relocations between Pasadena and Glen Burnie in the 1970s.

Maryland Route 667 (MD 667) is a state highway in the U.S. state of Maryland. The highway runs 17.61 miles (28.34 km) from Chesapeake Avenue in Crisfield east to U.S. Route 13 (US 13) in West Pocomoke. MD 667 forms the old alignment of MD 413 from Crisfield to Hudson Corner in southern Somerset County. The highway has a curvaceously course through the villages of Hopewell and Marion Station while MD 413 passes them on a straight course. The portion of MD 667 between Hudson Corner and West Pocomoke serves the community of Rehobeth. This segment, which was built as Maryland Route 406, serves as a shortcut allowing traffic between Crisfield and Pocomoke City to avoid Westover at the junction of MD 413 and US 13. Portions of MD 667 are part of the Blue Crab Scenic Byway and the Beach to Bay Indian Trail.The Crisfield–Westover highway was constructed in the 1910s and was numbered MD 413 in 1927. The present course of MD 413 was built from Crisfield to Marion Station in the late 1930s and early 1940s; MD 667 was assigned to the old segments of the highway. When modern MD 413 was completed from Marion Station to Westover in 1950, MD 667 was extended from Marion Station east and north to Westover along the old road. MD 406 started as a short segment of modern highway east from Hudson Corner in the late 1920s. That highway was extended east through Rehobeth to US 13 in the mid-1950s. MD 667 was removed from the Hudson Corner–Westover road and extended over the course of MD 406 to US 13 in 1961.
