The Shanghai Yangtze Bridge, located over open water at the entrance of the Yangtze River, is currently under construction. A cable-stayed bridge solution with the main span of 730m is adopted to meet the navigational demands of the main channel. The bridge comprises the dual-direction 6-lane expressway and 2-lane traffic railways. In fact, the 730m cable-stayed bridge over the main channel is the longest-spanning bridge of its kind for combined highway and railway traffic. The technical standard is studied to ensure the safety of railway and comfortableness of passengers for the combined highway and railway on the same plane. As the symbolic structure at the mouth of the Yangtze River, it also needs to take the aesthetics into consideration greatly. This paper presents the design and technical characteristics of the main channel cable-stayed bridge.
