The Sutro Tunnel is a drainage tunnel connected to the Comstock Lode—a massive deposit of silver ore—in Northern Nevada, conceived by Adolph Sutro as a means to allow access to deeper mineral exploration in the Comstock. Construction began in 1869, and the main tunnel was completed in 1878. The Sutro Tunnel pioneered the excavation of large drainage and access tunnels in the United States.
