Project Overview
VTA Bart to Silicon Valley Phase II Extension Project
The Santa Clara Valley Transportation Authority’s (VTA) BART Silicon Valley Extension Program (BSV Program) is the largest public infrastructure Program ever constructed in Santa Clara County. It includes the recently completed 10-mile, two-station Berryessa Extension Project (SVBX) and the Phase II Extension Project (BSVII Program).
Phase II is estimated to carry 54,600 passengers each weekday to destinations throughout the Bay Area by 2040. Completion of the project will finally "ring the bay" with frequent rail service. Phase II is planned to include:
CP2 Tunnel + Trackwork
Progressive Design-Build Schedule: Subject to Change
Tunnel Boring Machine
The BSVII Program will extend BART service from the existing temporary end of the SVBX line through downtown San Jose. The Phase II project will be delivered through four main construction packages (CP): Systems, Tunnel & Trackwork, Stations, and Santa Clara Station & Newhall Yard. The project will be delivered via the Progressive Design-Build delivery model.
CP2 includes a 5-mile long single-bore tunnel, extending from the terminus south of the recently opened Berryessa/North San José Station, through downtown San José along Santa Clara St, to the planned Newhall Maintenance Facility in the City of Santa Clara. The tunnel will be approximately 48 feet internal diameter, which will accommodate two BART trainways and will allow for the station platforms to be constructed within the tunnel.
The CP2 Tunnel and Trackwork contract will include procurement of the tunnel boring machine, utility relocations, portal enabling works and permanent structures, manufacturing and installation of the precast tunnel lining, construction of internal tunnel structures, construction of several ancillary ventilation/egress facilities, and excavation/support of three underground stations.
