From Wikipedia, the free encyclopedia

The Broadway Tunnel (San Francisco) is a highway tunnel in San Francisco, California, and carrys its namesake street underneath Russian Hill for about three blocks. 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.
