The world's highest and longest glass-bottomed bridge has been closed in China just 13 days after opening, because it was reportedly "overwhelmed" by visitors.

The 1,410ft (430 metre) bridge, which opened on August 20 and spans the Zhangjiajie Grand Canyon, in Hunan province, has a capacity of 8,000 visitors a day, but total demand is reported to be 10 times as much.

"We're overwhelmed by the volume of visitors," a spokesman from the Zhangjiajie Grand Canyon's marketing and sales department told CNN, explaining the bridge was the area's main attraction.

Designed by the Israeli architect Haim Dotan, the bridge leaves pedestrians suspended nearly 1,000ft (300 metres) above the canyon, allowing visitors to look down into the chasm through 99 triple-layered glass panels.
