Dumbarton Transportation Project

Enhancing Mobility for the San Francisco Bay Area

The objective of the Dumbarton Transportation Project is to enhance mobility between residential neighborhoods in the East Bay and job centers on the San Francisco Peninsula.

Shaking Hands in Partnership of Cross Bay Transit
Public-Private Partnership

The San Mateo County Transit District (District) and Cross Bay Transit Partners LLC (CBTP), a new company created by Plenary and Facebook, are engaged in a public-private partnership (P3) to improve transportation along this vital corridor in the South San Francisco Bay Area.

Project Process and Elements

Together, the District and CBTP are exploring new, environmentally appropriate alternatives for a high quality, high-capacity public transit system. Once identified and implemented, these proposed transportation improvements aim to bring commute alternatives along with job and housing opportunities to the Bay Area. The Project may also facilitate mixed-use transit-oriented development at key transit connections.
