The Sunset Tunnel is a 4,232 ft (1,290 m)-long light rail/streetcar tunnel in San Francisco, California. The tunnel runs under the steep hill adjacent to Buena Vista Park and is used exclusively by the N Judah Muni Metro line.
The tunnel was opened on October 21, 1928 in a ceremony presided over by Mayor James Rolph. The eastern entrance is located at Duboce and Noe streets on the south side of Duboce Park in the Duboce Triangle neighborhood, and the western portal is located in Richard Gamble Memorial Park near the intersection of Carl and Cole streets in the Cole Valley neighborhood.
Access to the tunnel is restricted to San Francisco Municipal Railway light rail trains only. Despite the access limitations, this tunnel is not well protected, and is constantly vandalized and graffiti-strewn. From time to time, automobile drivers manage to drive their cars into the tunnel.
The tunnel received seismic refitting and other renovations, which were completed in 2017. A combination of additional needed work that was discovered during construction, plus nearby residents challenging a night work permit, resulted in delays to the project and an additional $4 million cost for a total of $23.3 million.
