I've been on this!
Background: This curved pedestrian bridge is 2000 feet above sea level at the top of Mount Mat Cincang in Malaysia. Tourists who want to walk across the 400-foot long structure must ride up to it in a cable car.
Why It's Innovative: Set above the treetops, the Langkawi Sky Bridge is one of the highest elevated single-stay bridges in the world. The deck is less than 6 feet wide and its curved shape gives travelers a panoramic view of Langkawi, an archipelago of 99 islands. Each end is fitted with triangular observation decks.
