Hunan Aizhai Suspension Bridge

Under ADB financed Hunan Road III project, AiZhai Suspension Bridge was one of the key structures in the alignment. The bridge was the longest suspension bridge over a mountain valley in the World. The overall bridge length is 1,534 m with the main suspension span of 1,176 m and two side spans of 242 m and 116 m, respectively. The bridge spans over a deep mountain valley of about 330 m, which is one of the deepest valleys for a suspension bridge in the World.
