What you should know about 16th Street.
16th Street is best known for becoming the western portal of the Twin Peaks Tunnel, which opened on February 3, 1918, introducing the world's longest municipal streetcar tunnel at 11,920 feet and creating San Francisco's first rapid transit route beneath Twin Peaks, reducing cross city travel times, unlocking the large scale development of the Sunset and West Portal neighborhoods, and establishing the engineering foundation for the city's modern Muni Metro system that continues serving hundreds of thousands of passengers today.
The completion of the tunnel marked one of the most ambitious municipal transportation projects of its era, overcoming formidable geological challenges while permanently reshaping San Francisco's pattern of urban growth. The engineering achievement demonstrated how underground electric rail transit could connect previously isolated districts with downtown, stimulating residential construction, commercial investment, and long term economic expansion across the western half of the city. 16th Street continues expressing that extraordinary transportation legacy through a corridor that remains central to San Francisco's transit network more than a century after the tunnel first opened.
