What will construction be like?

Imagine yourself on Santa Clara Street near Market Street. During Phase II Project construction, the scene will look like today, unless you are outside one of our station or mid-tunnel facility sites. At those sites, construction will be limited within a fenced-in, well-lit construction staging area off-street. It will look like a low-rise typical building development as seen all around San José and Santa Clara.

VTA is able to limit construction impacts through innovative tunneling technology – a single-bore tunnel. Construction of a single-bore tunnel uses a tunnel boring machine, which will remove soil through the tunnel itself, keeping the street above intact. For project structures (stations and mid-tunnel facilities), construction will largely occur off-street, like buildings with underground parking. Intermittent driveway, access changes and lane closures will occur through construction. Detours will be provided for all transportation modes.
