Meet the Charles Kuonen Suspension Bridge, the longest pedestrian suspension bridge in the world right now. The newly opened bridge in Switzerland spans 1621 feet, and the highest point reaches 279 feet. That's as high as a 26-story building. The bridge also offers hikers with views of the Alps including the Matterhorn, Weisshorn, and Bernese Alps. If you ever have a chance to walk the bridge, you may not want to look down.
