The Wufengshan Yangtze River Bridge is a two-decked suspension bridge carrying the Lianyungang–Zhenjiang high-speed railway and the over the Yangtze.[1] With a total length of 6409m (21,027feet) and a main span of 1092m (3,583feet),[2] [3] it is the world's longest span high-speed railway bridge, tied with the Hutong Yangtze River Bridge.
Plans to build a railway bridge at the location had been conceived since the 1960s, but were shelved due to building techniques at the time being insufficient to meet the requirements.[4] Construction was started on 28 October 2015. The structure was closed on 29 December 2019[5] and the bridge was opened for railway traffic on 11 December 2020.[6]
The bridge is fitted with several measures such as dampers and tensioners to reduce deformation from wind, which would inhibit high-speed rail operation. The anchors of the bridge are of the largest ever built as a caisson, measuring 7260sqm, and weighing 1.33Mt. It also has the largest main cable diameter in the world, each cable contains 352 strands and has a diameter of 1300mm.
