en.Wedoany.com Reported - On May 12, with the final E40E41 steel girder section of Pier No. 3 (Shanghai side) hoisted into place, the single-cantilever steel girder erection for the main bridge of the Shanghai-Chongqing-Chengdu High-Speed Railway's Chongqi Yangtze River Rail-cum-Road Bridge, constructed by China Railway Group Limited Major Bridge Engineering Bureau, was fully completed. Currently, only one closure segment steel girder remains to be hoisted for the main navigable span bridge, with the main span closure planned for early June.

The Chongqi Yangtze River Rail-cum-Road Bridge is located in Jiangsu Province, China. It is the world's longest-span cable-stayed bridge for both road and rail traffic with a ballastless track, featuring a main span of 400 meters. The total length of the steel truss girder is 992 meters, with a total weight of approximately 36,000 tons. The construction adopted a scheme of incremental launching for the side spans and single-cantilever erection for the central span. The main navigable span bridge required the erection of 13 cantilever steel girder segments in total, with Piers No. 3 and No. 4 each erecting 6 segments in opposite directions using the single-cantilever method, plus 1 closure segment. Each individual steel girder panel is 12.5 meters long, with the heaviest segment weighing 918.4 tons. Erection was carried out symmetrically using two 1,100-ton capacity girder erection cranes, with stay cables installed concurrently with each steel girder segment.

The Chongqi Yangtze River Rail-cum-Road Bridge is a key control project for the Shanghai-Nanjing-Hefei High-Speed Railway. This line is the eastern section of the Shanghai-Chongqing-Chengdu High-Speed Railway and an important component of the Yangtze River Corridor High-Speed Railway, part of the national "Eight Vertical and Eight Horizontal" high-speed railway network. It undertakes the transport task of carrying the main passenger flow of the Yangtze River Corridor network, as well as some direct passenger flow to Shanghai from the coastal corridor and the Beijing-Shanghai corridor. Upon completion, the project will establish a new rapid passage connecting the Shanghai metropolitan area, the Nanjing metropolitan area, and the Hefei metropolitan area.
