BART Silicon Valley

BART Silicon Valley BART Silicon Valley Construction on the second phase of the project will commence as additional funding is secured.

VTA's Bay Area Rapid Transit (BART) Silicon Valley Extension is a 16-mile extension of the existing BART system to San Jose, Milpitas and Santa Clara, which will be delivered through a phased approach. The first phase, the Berryessa Extension, is a 10-mile, two-station extension, beginning in Fremont south of the future BART Warm Springs Station and proceeding in the former Union Pacific Railroad

right-of-way through Milpitas, the location of the first station, and then to the Berryessa area of north San Jose, at the second station. VTA continues project development activities for the second 6-mile phase of the project that includes a 5.1 mile-long subway tunnel through downtown San Jose, and ends at grade in Santa Clara near the Caltrain Station.

Cap beam installation has been completed at VTA’s BART Silicon Valley Phase II project. ➡️🔩

This is how the work comes together:

Reinforced concrete cap beams connect the tops of foundation piles together, helping distribute heavy loads and stabilize the structure.

Crews assemble and connect steel rebar cages, building the structure layer by layer.

Rebar cages are lifted into place, followed by wooden formwork before concrete is poured and set.

BSVII's July 2026 Construction Update is now live!

Construction is continuing at West Portal, where crews are advancing excavation and installing structural support systems within the launch structure.

Crews will also complete installation of monitoring equipment and remove temporary support elements as construction progresses into the next phase.

🚧 And a heads up for neighbors:

Ongoing excavation and steel bracing work may bring continued crane activity, haul trucks and intermittent steel handling noise throughout the area.

Expect intermittent construction noise, including overnight as work continues around the clock Monday through Saturday.

Confinement wall work has wrapped up at VTA’s BART Silicon Valley Phase II project, moving construction into its next phase. 🏗️🔩

Installed deep below the surface, these walls are made of reinforced concrete and help keep groundwater out while stabilizing surrounding soil.

Crews build the panels one at a time using specialized equipment to excavate, remove soil, and maintain stability before placing concrete.

Malcolm equipment is now being removed as this phase concludes, while crews continue preparing for Tunnel Boring Machine (TBM) entry and launch.

Major milestone! The West Portal Launch Structure excavation has reached the halfway mark, bringing VTA’s BART Silicon Valley Phase II project one step closer to the Tunnel Boring Machine (TBM) launch. 🚧🕳️

Crews are using large excavators to dig deep into the shaft and load soil onto trucks for removal. In harder to reach areas, cranes with buckets are being used to lift the soil out!

The work is done in stages to protect the structure’s walls and maintain safety throughout the process.

So far, crews have reached depths of about 47.5 feet and removed roughly 60,000 cubic yards!

Getting to the bottom of the launch structure safely and efficiently is a top priority at VTA’s Bart Silicon Valley Phase II West Portal site. 🏗️🛗

That’s why crews now have access to the project’s first construction elevator, fully installed and operational.

This highly durable elevator was installed using a concrete foundation with a steel mast anchored at the base.

A steel platform was then bolted into the concrete block at the launch structure to provide stability and support during site operations.

Fun fact: The elevator can carry up to 4,400 pounds!

The BART Silicon Valley Phase II Extension Project helps complete a more connected Bay Area, bringing us closer to the vision of “ringing the Bay with rail.” Faster trips, better access, and a more seamless transit network for generations to come.

Not all rebar is created equal, and some are designed to be cut. 🛠️

At the tunnel eye section of the Caterpillar Shaft, crews are using Glass Fiber Reinforced Polymer rebar (GFRP), a lightweight, non-corrosive alternative to steel.

The tunnel eye is reinforced with a combination of steel and GFRP rebar, spliced and connected.

When the Tunnel Boring Machine arrives, it will cut through the GFRP reinforced portion, supporting a smoother and safer breakthrough.

Fun fact: GFRP rebar is about four times lighter than steel and stronger in tension, making it ideal for this exact job.

BSVII's June 2026 Construction Update is now live!

Construction is continuing at West Portal, where crews are advancing excavation and underground support wall work to move the project forward.

Nearby neighbors may notice periodic crane activity, truck traffic and intermittent construction noise, including overnight.

At the 28th Street/Little Portugal Station site, crews will continue to conduct soils testing and drilling activities, with occasional drilling noise during weekday daytime hours.

🚧 And a heads up for drivers:

Utility work connecting gas infrastructure along Brokaw Road will finish up and will require temporary lane closures and detours, with increased traffic near the work zone.
