A 632-metre-long glass-bottomed bridge suspended 150 metres (490 feet) above a jungle has opened in Vietnam. The Bach Long (‘White Dragon’) pedestrian bridge is believed to be the world’s longest glass-bottomed bridge and is located in Vietnam’s northwest Son La province. Its floor is made from French-manufactured tempered glass, making it strong enough to support 450 people at a time.
