Mile Rock Tunnel, Utility tunnel in San Francisco, United States
Mile Rock Tunnel extends for 4,233 feet beneath San Francisco, connecting multiple districts including Sunset, West Mission, Richmond, and Ingleside districts.
Construction of the tunnel began in 1914 under Edward Malley, but R.C. Storrie and Company completed the project in 1915 after insurance complications.
The tunnel represents early twentieth-century municipal engineering solutions for managing urban water systems in rapidly developing San Francisco neighborhoods.
The tunnel continues to function as an essential storm drain overflow system, managing water drainage from multiple San Francisco districts through underground infrastructure.
Mayor Jim Rolph and City Engineer M.M. O'Shaughnessy conducted the first inspection of the tunnel by vehicle, requiring a reverse drive for the return journey.
