Daduhe Bridge Xingkang

Daduhe Bridge Xingkang 大渡河兴康特大桥 Luding, Sichuan, China 935 feet high / 285 meters high 3,609 foot span / 1,100 meter span 2018. Crossing a wide reservoir from a downstream dam just north of Luding city, the giant Daduhe suspension bridge is the largest structure on the Ya'an to Kangding expressway. Like many of China's Westernmost highways, this extension from the G5 expressway came many years after the more populous cities had already been connected in northern and eastern Sichuan Province. The Kanding route was especially difficult to construct with an amazing 82% of the road on bridges or in tunnels. Located at kilometer 99, the alignment chosen for the Daduhe Bridge resulted in an unusual design for the east end where the anchorages had to be placed high up inside the steep mountain slope. To avoid compromising the strength of the deep underground anchorage, the engineers split the east-west lanes apart into tunnels separated by more then 100 meters, keeping the alignment off to the sides of the cable anchorage. The deck of the Daduhe Bridge is approximately 235 meters above the full lake level or 285 meters to the original level of the Dadu River. The main cable has a 9.5:1 span to rise ratio. www.highestbridges.com
