Baldwin Street, The Steepest Street in The World

Located in the city of Dunedin, in southern New Zealand, the Baldwin Street has earned the distinction of being the steepest street in the world. This 350 meters long street begins with a moderate slope and then climbs steeply to reach a maximum slope of 1:2.86 or 19 degrees. In other words, the street rises by 1 meter for every 2.86 meters travelled horizontally. The street is so steep that it's surface had to be laid with concrete instead of asphalt otherwise on a warm day the tar would flow down the slope!

Baldwin Street is located in the residential suburb of North East Valley, running east from the valley of the Lindsay Creek up the side of Signal Hill towards Opoho. It rises about 70 meters along its length generating 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 are far steeper, and surfaced in concrete.
