The Shanghai-Nantong Railway Yangtze River Bridge, a joint project of railway and road construction, integrates the Shanghai-Nantong Railway, Yantong Railway, and Xitong Expressway, with a total length of 11.072 kilometers. It is located 45 kilometers upstream from the Jiangyin Yangtze River Bridge and 40 kilometers downstream from the Sutong Yangtze River Highway Bridge. The railway consists of four tracks, and the highway consists of six lanes. It is the world’s first combined road and railway cable-stayed bridge with a span of over a thousand meters. The design speeds are 100 kilometers per hour for the highway and 200-250 kilometers per hour for the railway. The area where the bridge is located has a subtropical humid monsoon climate with complex and variable weather conditions, prone to strong winds, especially severe typhoons, with wind speeds reaching up to 38.2 meters per second once in a century. In 2019, the company undertook the supply project for wind barriers for the Shanghai-Nantong Railway Yangtze River Bridge, covering approximately 300 meters. After the wind barriers were built, they effectively reduced the wind speed on the bridge deck, increased driving comfort and safety, and addressed the safety issues of vehicles driving in crosswinds during strong wind weather on the bridge.
