In preparation for construction of VTA’s BART Silicon Valley Phase II Extension Project, VTA’s tunnel and trackwork contractor, Kiewit, Shea, Traylor (KST) have developed a Construction Transportation Management Plan (CTMP) in coordination with the Cities of San José and Santa Clara and the BSVII Project Team. This plan is specifically for early construction activities at VTA’s Newhall Yard property, where the TBM will be launched (an area referred to as the west tunnel portal) and the location of the future Santa Clara Station. The purpose of this plan is to coordinate automobile, transit, bicycle, and pedestrian movements, truck hauling, general and emergency access, and reduce transportation impacts to the extent feasible during construction at and around the work site.   

The main purpose of early construction activities at the Newhall Yard property is to prepare the site for the launch of the TBM at the west tunnel portal. The west tunnel portal will be excavated and supported with reinforced concrete walls to create space for assembling and launching the TBM. Other early construction activities will include the construction of site entrances, a tunnel lining factory where tunnel lining segments will be constructed and stored before being placed in the tunnel, a grout plant to produce grout to seal the tunnel lining segments together, the excavated materials bin to store excavated materials until hauled offsite to be repurposed or disposed of, and a noise curtain along the west side of the site to reduce noise from construction activities, among other activities.  

Additional contract/area specific CTMPs will be developed by KST and future contractors for additional work areas as the project advances.  

Project Background 

VTA’s BART Silicon Valley Phase II Extension (Phase II Project) is a six-mile, four-station extension of BART from Berryessa / North San José Station (opened 2020) through downtown San José to the City of Santa Clara. The Phase II Project is planned to include an approx. five-mile subway, three stations with underground platforms (28th Street/ Little Portugal, Downtown San José, and Diridon), one ground-level station (Santa Clara), a train maintenance and storage facility, and additional facilities.
