Downtown San José station is a proposed underground Bay Area Rapid Transit station underneath Santa Clara Street in Downtown San Jose, planned as part of Silicon Valley BART extension Phase II. The station would be co-located with the Santa Clara Valley Transportation Authority's existing Santa Clara light rail station, and be located between the proposed 28th Street/Little Portugal station and a transfer station at San Jose Diridon Station. The station eventually connects to the proposed Santa Clara BART station. Revenue service, which will be served by the Orange and Green Lines, is envisioned to start in 2036.
