Daring tourists will soon be able to take a nerve-wracking walk 300 metres high between two cliffs - with a clear view of the bottom.
Workers in China were last week photographed installing the first piece of glass on what will be the world's longest and highest glass-bottom bridge.
Designed by Israeli architect Haim Dotan, the bridge is located in Zhangjiajie National Forest Park in the Hunan province.
It clocks in at 430 meters long and six meters wide, and hangs over a terrifying 300 metre drop.
