The 488-metre-long bridge at Hongyagu Scenic Area in Hebei, which opened on December 24, is the world’s longest glass-floor bridge. While it is designed to hold 3,000 people, only 600 people are allowed to cross the transparent glass walkway at any one time. To raise the excitement levels even further, the bridge is designed to sway when tourists walk across it. The opening of the bridge, which is suspended 218m above the ground and affords spectacular views of the surrounding countryside, was an immediate internet sensation. The bridge, which was built by Hebei Bailu Group, contains 1,077 glass panels and weighs about 70 tonnes. Crossing the bridge gives visitors stunning views of the mountains, waterfalls and river – assuming they can still bear to look at the scenery from such an elevated vantage point.
