ZHANGJIAJIE, CHINA — The much-awaited longest and highest glass-bottomed bridge in the world opened to visitors Saturday.
It's located in a scenic national park in central China's Hunan Province and spans two cliffs. The bridge is over one-quarter mile long and about 20 feet wide, hovering over a one-thousand foot vertical drop.
It looks from the air just like a giant white butterfly.
For the sake of safety, the glass-bottomed bridge only receives eight-thousand visitors per day at most. Appointments have to made at least one day ahead during the trial operation.
Paved with 99 panes of three-layered transparent glass, the bridge was completed last December at a cost of almost three and a half million dollars. It was originally scheduled to open in May.
