The Broadway Tunnel (officially the Robert C. Levy Tunnel) is a roadway tunnel in San Francisco, California. The tunnel opened in 1952, and serves as a high-capacity conduit for traffic between Chinatown and North Beach in the east and Russian Hill and Van Ness in the west. In a proposal of the city's 1948 Transportation Plan, the tunnel was to serve as a link between the Embarcadero Freeway and the Central Freeway.
The east portal is located just past the Mason Street overpass. The west portal is located just before the Hyde Street overpass. Combined with these two overpasses, the tunnel provides for uninterrupted traffic flow along Broadway for a stretch of six blocks, between Powell Street on the east and Larkin Street on the west.
