Golden Gate Bridge, Highway and Transportation District

The Golden Gate Bridge, Highway and Transportation District is a special-purpose district that owns and operates three regional transportation assets in the San Francisco Bay Area: the iconic Golden Gate Bridge, the Golden Gate Ferry system and the Golden Gate Transit system. All three assets connect Marin County with San Francisco. In the 1950s and 60s, officials in charge of the Golden Gate Bridge District coordinated to kill the popular BART extension into Marin County in order to preserve their own toll revenues.

History and responsibilities
The District was incorporated on December 4, 1928, as the Golden Gate Bridge and Highway District to design, construct, and finance the Golden Gate Bridge. The responsibility of regional transit service within the Golden Gate Corridor was given to the District on November 10, 1969, at which time it was given its current name.

The District's territory includes the City and County of San Francisco; Marin, Sonoma, and Del Norte counties; and large portions of Napa and Mendocino counties. The only other county along the California North Coast, Humboldt County, declined to join the district after its residents opposed the bridge's construction, fearing that the increase in tourists and newcomers would disrupt the local redwood lumber industry and various cattle and sheep ranches.

The District provides regional bus and ferry transit service throughout the Golden Gate Corridor, which runs from San Francisco to Sonoma County. The District does not operate transit service in Napa, Mendocino, or Del Norte counties. Within Marin County, Golden Gate Transit is the contractor for a majority of bus service provided by Marin Transit, a relationship that dates to 1971. Golden Gate Transit has operated bus service across the Richmond–San Rafael Bridge to Contra Costa County on behalf of the Metropolitan Transportation Commission since 1993.

The District's primary revenue source is tolling on the southbound lanes of the Golden Gate Bridge. (The last of the bridge's construction bonds were retired in 1971, with principal and interest raised entirely from bridge tolls. A mix of tolls, transportation subsidies, and grants is used to support bus and ferry services.
