Lombard Street's 'crookedest' block

The one-block section of Lombard Street between Hyde and Leavenworth features eight tight hairpin turns engineered in 1922 to reduce the hill's steepness for vehicles. The block has been widely promoted as the 'crookedest street in the world' and is a long-running piece of San Francisco tourist lore, though other streets make similar claims. The switchback design and its popularity for tourism and photography are well documented in city records and travel guides.
