The Shanghai-Nanjing High-Speed Railway Nanjing Hub project has achieved new progress at multiple key construction nodes.

On the 18th, as an important construction node of the Shanghai-Nanjing-Hefei high-speed railway Nanjing hub project, the Hu-Ning-Ning-Hefei high-speed railway Nanjing section control project - the Hu-Ning-Ning-Hefei high-speed railway Nanjing Liuhe Grand Bridge cross Ma Chahe cable-stayed bridge closure, marking the completion of all the continuous beam construction of the Nanjing Liuhe Grand Bridge of the Hu-Ning-Ning-Hefei high-speed railway, laying the foundation for the subsequent bridge deck construction and full-line connection. Recently, the Nanjing hub project of the Hu-Ning-Ning-Hefei high-speed railway has made progress in several key construction nodes. On January 7, the rotating body beam of the Nanjing Grand Bridge of the Hu-Ning-Ning-Hefei high-speed railway, with a total weight of 6300 tons, was rotated counterclockwise by 60 degrees, crossing the Beijing-Shanghai railway operating mainline, achieving precise rotation and laying the foundation for the subsequent box girder erection. On the evening of the 8th, the Nanjing Grand Bridge of the Hu-Ning-Ning-Hefei high-speed railway crossed the Chuzhou River cable-stayed bridge, achieving "precise handover" across hundreds of meters of water. The Hu-Ning-Ning-Hefei high-speed railway undertakes the transportation task of the main road network passenger flow along the Yangtze River, the direct passenger flow from the coastal and Beijing-Shanghai channels to Shanghai. After the project is completed, a new expressway will be built between the metropolitan areas of Shanghai, Nanjing, and Hefei, which is of great significance in building the "railway in the Yangtze River Delta" and optimizing the layout of the railway network in the Yangtze River area.
