Known as the 'Crookedest Street in the world', Lombard Street features eight sharp hairpin turns. The road was designed in 1922 in order to reduce the 72 degree slope of the hill and make it more usable for cars as well as pedestrians. The speed limit is a mere 5mph (8km/h) on the crooked section, which is about a quarter of a mile (400m) long. The crooked section of the street is reserved for one-way traffic travelling downhill and is paved with red bricks. Tourists are known to literally queue to drive down this famous road, making it a definite must-see when visiting San Francisco.
Address: Between Hyde and Leavenworth Streets, San Francisco
