The World's Steepest Street

Believe it or not, Baldwin Street, in the suburban part of Dunedin (達尼丁) (a southern city of New Zealand), is claimed as the world’s steepest street.

Baldwin Street is a short straight street, 350 metres long, rising from 30 metres (98 ft) above sea level at its junction with North Road to 100 metres (330 ft) above sea level at the top, an average slope of slightly more than 1 : 5. At its maximum, the slope of Baldwin Street is approximately 1 : 2.86 (19° or 35%).

From my rough measurement at the photos here, the street inclines at about 20 degrees to the horizontal. Heavy vehicles are advised not to climb this road.

In one of the photos, it seems that a house has sunk into the soil.

To experience the steepness of the road, the lady from a Taiwan TV team walked up the street and finally bought a certificate at NZ$2 from a local shop to certify that she had walked up the steepest road in the world.
