The Transbay Program is a visionary transportation and housing project that has transformed downtown San Francisco and the San Francisco Bay Area’s regional transportation system by creating a world class transportation hub in the heart of a new neighborhood. The project replaced the former Transbay Terminal at First and Mission streets in San Francisco with a modern regional transit hub connecting the Bay Area and ultimately the State of California through: AC Transit, BART, Caltrain, Golden Gate Transit, Greyhound, Muni, SamTrans, WestCAT Lynx, Amtrak, Paratransit and future High-Speed Rail from the San Francisco to Los Angeles/Anaheim.
