Throughout the history of Bay Area Rapid Transit, better known as BART, there have been plans to extend service to other areas. The Silicon Valley extension is under construction from Warm Springs to the Berryessa neighborhood station in San Bart train map pdf, linking BART to light rail in Santa Clara County.
900 million for the project in 2012. The extension broke ground in 2012, and had been scheduled for completion in 2016. Revenue service is expected in June 2018.
Service on this line will terminate at the Berryessa Station. Bay Point station to a Hillcrest Avenue station in Antioch, with an intermediate station at Railroad Avenue in Pittsburg.
Bay Point and Antioch is currently projected to begin in 2018. BART will eventually terminate at Santa Clara station. The original plan was for the extension to continue into downtown San Jose via subway.
The plans for the downtown subway start with a portal before crossing under US 101. The proposed Alum Rock subway station would be on North 28th Street between Julian Street and Santa Clara Street. The proposed Downtown San Jose station would be underneath Santa Clara Street spanning the block from 3rd Street to Market Street.
San Jose State University and Market Street. Arena station would be between SAP Center at San Jose and Diridon Station, which currently serves Amtrak, Caltrain, ACE and VTA Light Rail.
The BART subway would then turn north, following the Caltrain route, and exit to the surface at another portal after crossing under I-880. The proposed Santa Clara BART station would be co-located at the existing Santa Clara Caltrain station. For the subway segment in San Jose, VTA plans to use a tunnel boring machine for most of the length in order to reduce disruptions to downtown during construction.
