The world’s highest and longest glass-bottomed bridge opened to great fanfare on 22 August.<br />But just 13 days later the structure, which spans a spectacular canyon between two mountain cliffs in central Hunan province, has been forced to close.<br />The bridge is designed to hold up to 800 people and receive up to 8,000 visitors in a day, however demand has far outstripped capacity.<br />There are no reports of when the attraction will reopen.
