VTA’s BART Silicon Valley Extension Program (BSV) will expand BART service into Santa Clara County and is being built in two phases. Phase I (Complete) extended service from Alameda County into Santa Clara County Phase II (Currently in design and engineering) will extend service from the Berryessa Transit Center to the end of service in Santa Clara.

On Phase 1, JMA was the Design Unit Coordinator for the Guideway design unit from 60% to Request for Comments, which included the five cut-and-cover trench structures – Dixon Landing Road, Milpitas BART Station, Trade Zone Blvd, Hostetter Road and Sierra Road – over 10,700’ of trenching in total. JMA led the final design of the direct fixation track per BART Facilities Standards.
