Europe’s highest suspension bridge has opened to the public at Engelberg, Switzerland’s popular ski destination.The frighteningly high, 100-meter-long Titlis Cliff Walk, built along a section of Mount Titlis, was built in honor of the 100th anniversary of the Engelberg-Gerschnialp cableway, which began operating in 1913.Hanging approximately 3,000 meters above sea level, the bridge offers views that extend as far as 500 meters down "into the abyss of the south wall" on days with good visibility.“It is 100 percent safe and impossible to fall from the bridge,” Peter Reinle, the media representative for the Titlis Engelberg resort told CNN.The Cliff Walk has usurped Salbit Bridge, also located in Switzerland, as Europe’s highest suspension bridge.The route to the new bridge is a superlative journey in itself, passing through a 140-meter underground tunnel. Construction took four months and cost 1.5 million Swiss francs (US$1.6 million).The Cliff Walk is the latest addition to the attractions at Engelberg, which include spectacular ski and snowboard runs, a glacier cave, a glacier park and the first revolving cable car in the world.Reinle said that approximately 500 people had crossed the bridge since it opened to visitors on Friday, and that “most of the visitors had been impressed.”
