VTA's BART Silicon Valley Extension Project brings Bay Area Rapid Transit (BART) into Santa Clara County and rings the Bay with frequent rail service. The project is a planned 16-mile, six-station extension of the existing BART system and includes related projects and activities required to prepare the corridor for BART, such as relocation of existing Union Pacific Railroad tracks and utilities, drainage improvements, and grade separation projects within the alignment that are funded through other sources.
VTA's BART Silicon Valley Extension Project is managed by VTA in cooperation with BART. The complete extension is being built in two phases. Phase I, the Berryessa Extension, is a 10-mile, two-station project currently in testing and is anticipated to open for service in 2020. Phase II is a six-mile, four-station extension that will bring BART from Berryessa/North San José through downtown San José to the City of Santa Clara. The Phase II Project is planned to include an approximately five-mile tunnel, which includes three underground stations (28th Street/Little Portugal, Downtown San José, and Diridon), one ground-level station (Santa Clara), and general and maintenance facilities. Transit oriented communities are planned for each of the four station areas.
