A high-altitude suspension bridge with glass-bottomed opened Thursday in China. The bridge spans the gap between two cliffs at the Shiniuzhai National Geological Park in Pingjiang County, Hunan province, and is thought to be the highest glass-bottomed bridge in the country. The bridge, called “Haohan Qiao” in Chinese, spans a 300-metre canyon and is 180 metres above ground. [Images via Sina]
