The Broadway 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 to the east and Russian Hill and Van Ness Avenue to the west. In a proposal of the city's 1948 Trafficways Plan, the tunnel was to serve as a link between the Embarcadero Freeway and the Central Freeway.
