Building a road 626 metres above a river meant joining large steel sections into one deck at China’s Huajiang Bridge. Below the builders lay a deep gorge in Guizhou province. Guinness World Records lists the result as the world’s highest bridge.
The suspension bridge opened on 28 September 2025. Its 2,890-metre length links the two sides of the gorge. The main span, the distance between the principal towers, measures 1,420 metres.
Hangers support the road deck from the main cables. Those pass over towers and are firmly anchored at the ends. The weight of the bridge and traffic passes through cables, towers and anchorages into the ground.
Builder CREC describes 93 steel installation segments for the main girder structure. These large sections had to form a precisely aligned whole at height.
Before opening, the bridge underwent heavy load tests. CREC reports up to 96 trucks weighing more than 3,300 tonnes together. Measurements examined the main cables, hangers, girder, towers and anchor blocks.
