Many tourists queued up overnight to be the first to visit the attraction.The 430m-long bridge cost $3.4m (£2.6m) to build and stands 300m above ground being paved with 99 panes of three-layered transparent glass. It was designed by Israeli architect Haim Dotan. Officials even drove a car, filled with passengers, across the bridge, to prove it’s safety. Park officials have said a maximum of 8,000 visitors will be allowed on the bridge each day. Tourists will have to book their tickets a day in advance, at a cost of 138 yuan (£15.94). The more adventurous will be able to bungee jump or ride a zip line. The bridge became incredibly crowded in a short time after the opening. Cameras and selfie sticks are banned. One of the summits in Zhangjiajie Park inspired the floating mountain which appears in the American blockbuster Avatar.
