Fort Mason Tunnel is an abandoned single-track railway tunnel in San Francisco. It was built in 1914 to bypass Fort Mason. The east portal is near the north end of Van Ness Avenue; the west portal feeds onto Marina Boulevard at Laguna Street.
The tunnel's construction in 1914 served several purposes. The rail link supplied goods and mass transit to the Panama Pacific International Exposition the following year; the U.S. Army utilized the line for construction of the Port of Embarkation. The tunnel operated as part of the State Belt Railroad until the route's suspension in 1993.
Fort Mason extension
In 2012, the National Park Service released a final environmental impact report on providing extended service through the tunnel to the San Francisco Municipal Railway F Market & Wharves line. The cost of refurbishment and extension of the rail line was estimated at $60 million in 2017.
