The World’s Most Majestically Terrifying Skywalks
In 2007, a 70-foot-long pedestrian bridge was built out over the edge of the Grand Canyon. The glass beneath tourists’ feet was all that separated them from the Colorado river and the canyon floor, 720 feet below. This would, naturally, scare some, and, just as naturally, attract perhaps even more. The Grand Canyon skywalk was a hit and, since then, similar structures have been built all over the world. The most recent high-profile project–the 984-foot-long Haohan Qiao glass bridge in China’s Hunan Province–is perhaps the most audacious yet. See more of the world’s thrilling skywalks at Smithsonian.
