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. Learn more about Phase I here. Phase II (Currently in design and engineering) will extend service from the Berryessa Transit Center to the end of service in Santa Clara. For Phase 2, JMA has completed the early works design for the West Portal project where a 5-mile-long bored single bore tunnel will extend from Berryessa/North San Jose station, through downtown San Jose along Santa Clara St, to the proposed Newhall Maintenance Facility. JMA supported the prime contractor with site grading and drainage, utility design, QA/QC, and the preparation of the Construction Transportation Management Plan (CTMP). Additionally, JMA prepared a system-wide Basis of Design report for the West Portal, Diridon Station, Downtown San Jose Station, 28th Street Station, and East Portal, and led construction support for the enabling works. Design was completed in 2023, and the West Portal groundbreaking took place in June 2024.
