4. Most Crooked Street in US, Lombard St – San Francisco, USA
The street is famous for a small section near the top of Russian Hill, between Hyde and Leavenworth streets. Here the hill is so steep (27°) that it would be too dangerous for most vehicles, so between 1922 and 1923 this part of Lombard Street was transformed into a switchback with eight sharp turns. Cars can only drive downhill, east-bound towards Leavenworth Street.
The crooked section of the street, which is about 1/4 mile (400 m) long, is reserved for one-way traffic traveling east (downhill) and is paved with red bricks. The speed limit in this section is 5 miles per hour (8.0 km/h).
5. The Steepest Street in the World, Baldwin Street – New Zealand
Baldwin Street in a suburban part of New Zealand's southern city of Dunedin, is considered the world's steepest residential street. It is located in the suburb of North East Valley, 3.5 kilometres (2.2 mi) northeast of Dunedin's city centre.
A short straight street a little under 350 metres (1,150 ft) long, Baldwin Street runs east from the valley of the Lindsay Creek up the side of Signal Hill towards Opoho, rising from 30 m (98 ft) above sea level at its junction with North Road to 100 m (330 ft) above sea level at the top, an average slope of slightly more than 1:5. Its lower reaches are only moderately steep, and the surface is asphalt, but the upper reaches of this cul-de-sac are far steeper, and surfaced in concrete (200 m (660 ft) long), for ease of maintenance and for safety in Dunedin's frosty winters. At its maximum, the slope of Baldwin Street is about 1:2.86 (19° or 35%) – that is, for every 2.86 metres travelled horizontally, the elevation rises by 1 metre.
