Recently, the cable-stayed bridge over the Shanghai Xietang Channel of the Shanghai Suzhou Lake Railway was successfully completed, marking the completion of the main structure of the special span bridge with the largest span and the most difficult construction of the Shanghai Suzhou Lake high-speed railway. Significant breakthroughs have been made in the construction of key and difficult control projects along the entire line, laying a solid foundation for the completion and opening of the entire line.

The Hu Su Hu high-speed railway starts from Shanghai Hongqiao Station, passes through Suzhou City, Jiangsu Province, and ends at Huzhou Station in Huzhou City, Zhejiang Province. The total length of the main line is about 163.8 kilometers. The cable-stayed bridge of the Shanghai Suzhou Lake high-speed railway crossing the Xietang channel is four parallel bridges of the Shanghai Suzhou Lake high-speed railway with a speed of 350 kilometers per hour and the Shanghai Kunming railway with a speed of 160 kilometers per hour. The total length of the bridge is 460 meters, and the main span is 260 meters. It is the first bridge of the four parallel lines of the 350 kilometer high-speed railway and the ordinary speed railway. At the same time, this bridge is the first to use a double-sided box steel-concrete composite beam form, using advanced ballastless track technology to enhance smoothness and stability, and overall reaches the international advanced level.
