The much-heralded "world's highest and longest" glass-bottomed bridge has opened to visitors in central China.
It connects two mountain cliffs in what are known as the Avatar mountains (the film was shot here) in Zhangjiajie, Hunan province.
Completed in December, the 430m-long bridge cost $3.4m (£2.6m) to build and stands 300m above ground, state news agency Xinhua reported.
It has been paved with 99 panes of three-layered transparent glass.
