Baldwin Street is a street 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.
