Lombard Street is an east–west street in San Francisco, California that is famous for a steep, one-block section with eight hairpin turns. Stretching from The Presidio east to The Embarcadero (with a gap on Telegraph Hill), most of the street's western segment is a major thoroughfare designated as part of U.S. Route 101. The famous one-block section, claimed as "the crookedest street in the world", is located along the eastern segment in the Russian Hill neighborhood. The street was named after Lombard Street in Philadelphia by San Francisco surveyor Jasper O'Farrell.Route descriptionLombard Street's west end is at Presidio Boulevard inside The Presidio; it then heads east through the Cow Hollow neighborhood. For twelve blocks, between Broderick Street and Van Ness Avenue, it is an arterial road that is co-signed as U.S. Route 101. Lombard Street continues through the Russian Hill neighborhood and to the Telegraph Hill neighborhood. At Telegraph Hill it turns south, becoming Telegraph Hill Boulevard to Pioneer Park and Coit Tower. Lombard Street starts again at Winthrop Street and ends at The Embarcadero as a collector road.
