Passerelle Mont Saint-Michel - Mont-Saint-Michel, France
Off the northwestern coast of France lies Mont-Saint-Michel, a small island commune and UNESCO World Heritage site. And in 2014, a 2,500-foot pedestrian bridge was constructed so that you can arrive at the island the same way pilgrims would during low tide: on foot. Plus, you don't have to worry about getting stranded when the tide comes in.
