Zhangjiajie Glass Bridge – Zhangjiajie, China

The Zhangjiajie Glass Bridge in central China opened to the public in August 2016. It’s currently the longest and highest glass-bottomed bridge in the world. The suspension bridge, which joins two mountain cliffs in the Hunan region, is made up of metal frames with over 120 glass panels making up the flooring. The bridge can handle a maximum load of 8,000 people per day. The transparent bridge rises up 300 meters from the gorge below and stretches out over a 430-meter distance. To demonstrate the structure’s strength and safety, its authorities allowed the public to crash its glass panels with mallets and shockingly drove a car across it.
