Daredevils wanting to cross China's first all-glass bridge, suspended 180 meters over a canyon in Hunan Province, during the National Day holiday may have to be patient -- the local government has capped visitor numbers.

Pingjiang County has set the maximum number of daily visitors to Shiniuzhai Scenic Zone at 10,000 until Thursday.

It received 20,000 visitors on Friday, the second day of the week-long vocation.

The 300-meter-long and two-meter-wide walkway was opened to the public on Sept. 24 after having been under construction for two years.

Zone executives stressed the decision was made because of the overall capacity of the park, not because of safety fears about the bridge, which is made of two layers of hardened glass, 24 millimeters thick in total.

Hunan is slated to open a longer and higher glass bridge later this year over Zhangjiajie Grand Canyon.
