The world’s highest glass bottom bridge, in China’s Hunan province, opens this weekend connecting two mountain cliffs. It is 300 meters above ground, 6 meters wide and 430 meters total length. There are 99 panes of the three-layered glass laid along the center of the bridge and will open to 8000 tourists a day. Construction of the bridge was completed in December but safety testing recently finished.
