Amazing Eshima Ohashi bridge in Japan, the third-largest in the world, appears to have an extraordinarily steep incline on both sides, so ships can easily pass underneath.

The incredible two-lane concrete road bridge connects the cities of Matsue and Sakaiminato, which spans across Lake Nakaumi. The bridge reaches a length of 1.7 kilometers and has a width of 11.4 meters, with a 5.1 percent and 6.1 percent gradient on each side.

The unusual steep bridge was recently featured in a commercial for Daihatsu Motor Co's Tanto minivan to test the vehicle's durability.

The bridge reaches a height of 44 meters, giving it a rollercoaster-like appearance. [Photo/IC]
