 The sale of several land parcels formerly owned by the state and given to the managing Transbay Joint Powers Authority helped finance the construction of the Transit Center.The original Transbay Terminal opened in 1939 as the San Francisco terminus for the Key System and other commuter trains that travelled across the new San Francisco–Oakland Bay Bridge to the East Bay.Train service to San Francisco was discontinued in 1958 and the Transbay Terminal was reconfigured for buses.
