Zhangjiajie Glass Bridge (also called Zhangjiajie Grand Canyon Glass Bridge) is a bridge in Zhangjiajie, China, above the Wulingyuanarea. The bridge, built as an attraction for tourists, is glass-bottomed and is transparent. When it opened it was the longest and tallest glass bottomed bridge in the world. The bridge, opened to the public on August 20, 2016, measures 430 metres in total length and 6 metres in breadth, and is suspended about 260 metres above the ground. The bridge spans the canyon between two mountain cliffs in Zhangjiajie National Forest Park in China’s central Hunan province. It is designed to carry up to 800 visitors at a time. The bridge was designed by Israeli architect Haim Dotan.
To build the bridge, engineers erected 4 support pillars on the edges of the walls of the canyon. The bridge is made of a steel frame with more than 120 glass panels. Each of these panels is 3-layered and is a 2-inch-thick slab of tempered glass. There are 3 long swingsattached to the underside of the bridge. Also there is a provision for making an 870-foot bungee-jump. This is considered to be highest such jump in the world.
