Excerpt from Wikipedia
The Wufengshan Yangtze River Bridge (Chinese: 五峰山长江大桥) is a two-decked suspension bridge carrying the Lianyungang–Zhenjiang high-speed railway and the Jiangyi Expressway [zh] over the Yangtze. With a total length of 6,409 m (21,027 ft) and a main span of 1,092 m (3,583 ft), it is the world's longest span high-speed railway bridge, tied with the Hutong Yangtze River Bridge.
History
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. Construction was started on 28 October 2015. The structure was closed on 29 December 2019 and the bridge was opened for railway traffic on 11 December 2020.
Engineering
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 7,260 m² (78,100 sq ft), and weighing 1.33 megatonnes (2.9×109 lb). It also has the largest main cable diameter in the world, each cable contains 352 strands and has a diameter of 1,300 mm (51 in).
