#4 Traversinertobel - Switzerland

Jurg Conzett and associate Rolf Bachofner designed the bridge over the Traversinertoboel. The last of it's kind, the bridge connects two elevations over a gorge in Via Mala. Replacing a rope bridge, that was wiped out during a landslide, the staircase covers more than 183 feet.
