The Eshima Ohashi Bridge in Japan, which spans a mile across Lake Nakaumi linking the cities of Matsue and Sakaiminato, definitely looks more like a rollercoaster than a bridge. The two-lane concrete road bridge stretches just over 1 mile (1.7 km) long and has a width of 37.4 feet (11.4 meters), making it the largest rigid frame bridge in Japan and the third-largest in the world. Combine that with a grade of 6.1 percent, and this bridge is pretty daunting.
Would you want to drive on that road? It’s basically a highway to outer space, a shortcut to vomiting from nausea.
