Baldwin Street in NZ is said to be the world's steepest residential street
Baldwin Street is located in Dunedin, New Zealand. It’s considered the world's steepest residential street. The angle is 35 per cent - but the steepest section is made from concrete because asphalt would run down the hill on a hot day.
It takes about ten minutes, just to walk about 350 metres. At its maximum, the slope of Baldwin Street is approximately 1:2.86 (35%) - that is, for every 2.86 metres travelled horizontally, the elevation rises by 1 metre.
