The world’s longest glass bridge was opened to the public at Huaxi World Adventure Park, in east China's Jiangsu Province, earlier this year.<br /><br />Hanging more than 100 metres above ground level, the 518-metre long bridge is reportedly made of special glass with a thickness of 3.5 centimetres. The bridge can support up to 2,600 people at a time.<br /><br />Seeing the chasm under their feet, visitors from all over the world pay to have the sensation of walking on air.
