The other three contract packages which will be delivered via design-build include the contract for the build-out of three underground stations with above-ground entrances and ticketing; the systems contract; and the above-ground station and rail yard.

The six-mile, BART (Bay Area Rapid Transport) Phase II Extension Project will extend southwest from the recently opened Berryessa/North San José Station, with three more underground stations in San Jose and one above-grade station in Santa Clara. Five miles of the alignment will be underground.

Construction is planned to begin in 2022, with substantial construction completed by 2028.
