Dumbarton Express is a regional public transit service in the San Francisco Bay Area connecting Alameda, San Mateo, and Santa Clara Counties via the Dumbarton Bridge.
The Transbay bus service is provided under a consortium of five transit operators (AC Transit, BART, SamTrans, Union City Transit, and VTA).
Dumbarton Express is administered by AC Transit.
It was also operated by AC Transit through 16 December 2011; MV Transportation assumed operations effective 19 December 2011.
AC Transit also operates bus service across the Dumbarton Bridge on Route U, which connects Fremont BART and Stanford University.
Route U is not part of the Dumbarton Express system.

Future expansion
On August 2, 2017, SamTrans, one of the five transit agencies that jointly operate the Dumbarton Express, released a study that examined the feasibility of adding additional bus routes to the service.
The study recommended two new bus routes: an express bus route traveling between the Union City BART station to the Redwood City Caltrain station, and a local bus route between the Union City BART station to job centers in northern Mountain View and Sunnyvale, the introduction of which would lead to a 34% increase in ridership.
The study also reiterated SamTrans' ultimate goal of reintroducing rail service across the Dumbarton Rail Bridge, ultimately connecting the Redwood City Caltrain station to the Union City BART station via conventional passenger rail.
