The Silicon Valley BART Extension is an ongoing effort to expand service by Bay Area Rapid Transit (BART) into Santa Clara County from its former terminus at the Fremont station in Alameda County. Planned since at least 1981, the project has seven stations in three sequential phases. The first phase was the Warm Springs BART extension, built by BART at a cost of $790 million, terminating at the new Warm Springs/South Fremont station that opened in 2017. The Warm Springs extension broke ground in 2009, and was originally scheduled for completion in 2014. The $2.3-billion second phase, known as phase I of Silicon Valley BART Extension or the Berryessa extension, includes two new stations, the Milpitas and Berryessa/North San Jose stations. The Berryessa extension broke ground in 2012, and was originally scheduled for completion in 2016. It is scheduled to open on June 13, 2020. The Santa Clara Valley Transportation Authority (VTA) is building the Berryessa extension, while BART will operate and maintain the entire extension. The two agencies have had differing timelines for the start of service, with VTA's being more optimistic. BART has expressed caution as to the timeline. The $5.6-billion third phase to downtown San Jose remains unfunded. Targeted for completion in 2029–2030, it would add three new subway stations south of Berryessa: Alum Rock/28th Street, Downtown San Jose, Diridon, and a surface station in Santa Clara. Initial testing and preliminary construction activities began in January 2019.
