The San Francisco Transbay Terminal or The Transbay Terminal, was a transportation complex in San Francisco, California, United States, roughly in the center of the rectangle bounded north–south by Mission Street and Howard Street, and east–west by Beale Street and 2nd Street in the South of Market area of the city. It opened on January 14th, 1939 as a train station and was converted into a bus depot in 1959. The terminal mainly served San Francisco's downtown and Financial District, as transportation from surrounding communities of the Bay Area terminated there such as: Golden Gate Transit buses from Marin County, AC Transit buses from the East Bay, and SamTrans buses from San Mateo County. Long-distance buses from beyond the Bay Area such as Greyhound and Amtrak also served the terminal. Several bus lines of the San Francisco Municipal Railway connected with the terminal.It closed on August 7, 2010, to make way for the construction of the replacement facility, the Transbay Transit Center, and associated towers. All long-distance and transbay bus operations were transferred to a Temporary Transbay Terminal at the nearby block bounded by Main, Folsom, Beale, and Howard Streets.
