Golden Gate Transit is one of three transportation systems owned and operated by the Golden Gate Bridge, Highway and Transportation District; the others are the Golden Gate Bridge and Golden Gate Ferry, both of which connect San Francisco and Marin County. Funding for cross-bridge "Transbay" bus service is partially subsidized by Golden Gate Bridge tolls in addition to traditional federal and state sources. GGT operates some bus service within Marin County under contract with Marin Transit.
