Transbay Joint Powers Authority

The Transbay Transit Center Program (Program) is an approximately $6 billion program to replace the former Transbay Terminal at First and Mission streets in San Francisco with a modern regional transit station that will connect eight Bay Area counties and the State of California through eleven transit systems: Alameda–Contra Costa Transit, BART (Bay Area Rapid Transit), Caltrain, Golden Gate Transit, Greyhound, Muni (San Francisco municipal bus lines), SamTrans (San Mateo County Transit), WestCAT (Western Contra Costa Transit) Lynx, Amtrak, Paratransit, and high-speed rail from San Francisco to Los Angeles/Anaheim.

The Program will be constructed in two phases. Phase 1 includes design and construction of the above-grade portion of the Transit Center, including a 5.4-acre park, retail areas, and a public art program; the core and shell of the two below-grade levels of the train station; a new bus ramp; a bus storage facility; and a temporary bus terminal. The Downtown Rail Extension (DTX) tunnel, the build-out of the below-grade train station facilities at the Transit Center, a pedestrian tunnel connecting the Transit Center with the Embarcadero BART/Muni Metro station, a new underground station, and an intercity bus facility will follow as Phase 2 of the Program.
