China opens world's longest glass-bottomed bridge
Some 430 metres (1,400 feet) long and suspended 300 metres above the earth, the bridge spans the canyon between two mountain cliffs in Zhangjiajie park in China's central Hunan province. Six metres wide and made of some 99 panels of clear glass, the bridge can carry up to 800 people at the same time, an official in Zhangjiajie -- a popular tourist destination -- told the Xinhua news agency. Following an alarming glass bridge cracking incident at the Yuntai mountain in northern Henan in 2015, authorities in Zhangjiajie were eager to demonstrate the safety of the structure.
