The Shanghe-Hangzhou Railway is an important part of the national railway trunk line in the country's medium and long-term railway network. It is also an important part of my country's eight vertical and eight horizontal railway network and the Beijing-Hong Kong-Kowloon high-speed rail line. The control project of Shanghe-Hangzhou Railway-Wuhu Yangtze River Highway and Railway Bridge is a super-large bridge that integrates high-speed rail, rail transit and urban main roads. The upper layer is a two-way eight-lane highway with light rail on one side and high-speed rail on the other. The main span of the bridge is 588 meters, with No.2 main tower 155 meters high and No.3 main tower 130.5 meters high. The height of the main tower above the bridge deck is only half of the normal tower height, and it is the world's first high and low tower dual-purpose cable-stayed bridge.
