Switzerland has opened the world's longest suspension footbridge. It is 494 meters long. The bridge is suspended between 1,600 meters and 2,200 meters above sea level. It is only 65 centimeters wide and goes as high as 85 meters above the ground. Hikers, within sight of the famed mountain, the Matterhorn, and the Bernese Alps, can cross it in about 10 minutes. The bridge crosses the deepest-cut valley in Switzerland. Hikers can look down onto it through grates in the bridge. Without the bridge, the journey previously took up to four hours. According to Swiss reports, it took only 10 weeks to build the bridge.
