The World's Longest Bridge

For a guy like me who is afraid of heights, you may never catch me walking on this bridge. The Europe Bridge spans 494m and hangs up to 85m above a ravine near the town of Zermatt, and has a system in place to prevent swinging.

The bridge for hikers billed as the longest hanging pedestrian bridge in the world has opened in Switzerland. China has built five of the 10 longest suspension bridges in the world, including the Xihoumen bridge. It's a man-made wonder, the world's highest (and maybe even scariest) tunnel-to-tunnel bridge.
