Japan | Kawazu-Nanadaru Loop Bridge

The Kawazu-Nanadaru Loop Bridge, in Japan, is an example of how to build a bridge from one mountainside to another when the sides of the mountain are so steep that it is not possible to build a road at the same elevation on both sides. It’s one of the most spectacular bridges in the world. This double spiral brings cars up and down a full 45 meters (148 feet) while being seemingly suspended in a valley between two mountainsides.
