Located in Tottori Prefecture of Western Japan, the Eshima Ohashi Bridge looks more like a roller coaster than a road. It is basically a highway to outer space, a shortcut to vomiting from nausea, making driving over this thing one seriously thrilling car ride. It's one of the most spectacular bridges in the world.
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.
