Introduction to the Glass Bridge: The glass bridge in the Zhangjiajie Grand Canyon is the highest and longest-span glass bridge in the world. It is built on the peaks on both sides of the Grand Canyon. The relative height of the bridge arch from the valley bottom is about 400 meters, and the total length is about 370 meters. The bridge deck is entirely paved with transparent glass, and there is the world's highest bungee jump in the center of the bridge. Standing on the bridge, you can have a panoramic view of the valley below. The two glass auxiliary bridges are ancillary preliminary projects of the main glass bridge, with heights of 12 meters and 15 meters respectively. One is located on the water 9 meters deep, 3 meters away from the water, and the other is located on the canyon. They are a pair of "sister bridges".
