The Zhangjiajie Park Footbridge is the 3rd highest footbridge in the world after the Tianjishan and Niouc bridges. Located in one of China's most spectacular National Parks, the beam-truss bridge is crossed by thousands of tourists every year who marvel at the deep crevasse below the see-through grate. This jaw-dropping abyss puts the Zhangjiajie Footbridge ahead of any high bridge in the world for having the greatest ratio of height to span length with a vertical drop 6.5 times greater then its span length. This exceeds even France's Chatelet Bridge which has the world's second greatest drop to span ratio of 6 to 1.

The deck is supported on steel I-beams punctuated with oval-shaped holes. Above the walkway there are a series of steel tubes that form a kind of Vierendeel truss where there are no diagonal members. This unusual design may be the cause of an odd phenomenon where the bridge continually oscillates from side to side when tourists are on the bridge. This movement is small - probably just a few centimeters - but it caused a number of tourists to feel uncomfortable. A simple series of diagonal beams below the deck would eliminate the problem. But the best solution might be a complete replacement of the entire span with a prettier and more natural looking stone arch bridge.
