VTA's BART Silicon Valley Extension Program

VTA’s BART Silicon Valley Extension Program (BSV) will expand BART service into Santa Clara County, bringing frequent and reliable regional rail service to over 1.7 million county residents.  The project is being built in two phases.

  • Phase I will extend service from Alameda County into Santa Clara County, with stops at Milpitas and Berryessa/North San Jose. Service is planned to begin in late 2019.
  • Phase II, currently in design and engineering, will extend service from the Berryessa Transit Center to stations at Alum Rock/28th Street, Downtown San Jose, Diridon Station with the end of service in Santa Clara.

More than a transit project, BSV is an entire program of improvements that will transform Silicon Valley.  Facets of the project include transit oriented communities, multimodal transportation connectivity, as well as roadway, utility and environmental improvements.

Project History 

The effort to bring BART into Santa Clara County has been decades in the making. 

When the BART District was formed in the 1960's, Santa Clara County opted out. Faced with growing congestion along the I-880 corridor, a Major Investment Study was conducted in 2001 which identified the need for transit alternatives and laid the groundwork to start the environmental process for the BART Silicon Valley Extension Program.  

The original project would have extended service in one 16 mile extension from South Fremont to Santa Clara. The VTA  Board committed to building the project in two phases in February 2009, with Phase I carrying passengers to Berryessa/North San Jose and Phase II serving downtown San Jose to Santa Clara.

Phase I broke ground in 2012 and is anticipated to open for passenger service by late 2019.

Phase II has completed the environmental process and is currently in the design and engineering process.
