Last beam laid on record-long glass bridge
Print Edition
THE final beam of the world’s longest and highest glass bridge was laid yesterday.
Those with a stomach for heights can now walk across the 400-meter deep Grand Canyon at Zhangjiajie National Forest Park in central China’s Hunan Province, on glass.
The 430-meter long, 6-meter wide bridge is the world’s longest open space suspension bridge, and boasts the world’s steepest ziptreck and highest Bungee platform.
The bridge will be open to the public by May 1, 2016.
Chen Zhidong, from Zhangjiajie Scenic Area Management Co, said the structure had undergone nearly 100 safety tests to ensure it can support the weight of 800 people.
More than 70 glass balls, each weighing 750 kilos, have been installed to counter sympathetic vibration, said Wan Tianbao, a chief engineer with the project.
Wan said the glass had passed wind, slippage and temperature resistance tests.
Zhangjiajie also boasts another all-glass bridge that suspends 180 meters above another canyon. After it was opened to the public in September this year, it was so popular that visitor numbers were limited to 10,000 a day over safety concerns.
Zhangjiajie inspired the scenery in the hit movie “Avatar,” and members of the production team spent time there taking notes and sketches that would form elements of the animation.
