Eshima Ohashi Bridge

Japan

For this bridge, it’s all about perspective. While it looks like the steep incline of a roller coaster, the bridge is a mile long, linking the cities of Matsue and Sakaiminato. While it looks like an insane incline, it’s actually an optical illusion. One side of the bridge has a 6.1% grade, while the other has a 5.1% grade. When you look at it from the side, it’s a gentle rise, but from the front/back, it looks dangerously steep.
