The BART To Silicon Valley (Fremont/Milpitas/San Jose) Project


MISSION: Bay Area Rapid Transit makes travel easier for thousands upon thousands of riders in San Francisco, Alameda and Contra Costa counties—but past efforts to expand to Santa Clara county failed...until now. In 2011, work began on an extension from Fremont into San Jose that is scheduled to wrap in 2017-18, depending on the source.

Long-term plans call for the route to loop all the way through downtown San Jose into Santa Clara; funding currently isn't available and won't be until at least a couple more years (as of 2015).


Funding permitted, BART tentatively hopes to complete the latter extension phase by 2025.


Obviously, changes must be made to accomodate the new railway, which will run along existing railroad tracks (mostly Union Pacific) for the majority of its route.

From the existing southern terminus at Fremont Station moving southward, new stations are being added at:

  • Warm Springs (off Warm Springs Blvd just south of Grimmer in Fremont); this station is set to open any month now,  

  • Milpitas (Montague Expressway & Capitol Avenue at Milpitas/San Jose edge), and

  • Berryessa (near the intersection of Berryessa and King/Lundy in San Jose).


Phase II planned stations include:

  • Alum Rock (elevated near Santa Clara St/Alum Rock Avenue overpass at US-101 in San Jose)

  • San Jose Downtown (near the intersection of Santa Clara/Market Streets in San Jose, via subway under Santa Clara Street) and

  • Santa Clara (at the existing CalTrain station across El Camino from Santa Clara University).


Existing roads requiring modification for this project:


  • Warren Avenue, Fremont (underpass built)

  • Kato Avenue, Fremont (underpass built)

  • Dixon Landing Road, Fremont (underpass built)

  • Montague Expressway, San Jose (trench under road built)

  • Trade Zone Boulevard, San Jose (trench under road built)

  • Sierra Road/Lundy Avenue intersection, San Jose (tunnel built underneath intersection)

  • Hostetter Road, San Jose (trench under road being built)


Several roads in the path of BART already have grade separations in place for the UPRR, such as Jacklin Road and Calaveras Boulevard in Milpitas. Obviously, no modifications will be required on such roads. Washington Avenue and Paseo Padre Parkway in Fremont were reconfigured as underpasses in anticipation of a Warm Springs BART extension back in 2010.
