The Wushan Yangtze River Highway Bridge is a half-way CFST arch bridge with a main net span of 460 m. The main arch rib is supported by a cable-stayed cable-stayed suspension cable and was successfully closed in mid-April 2003. The bridge is to further improve China’s unshielded cable hoisting system. Some of its key technologies in hoisting construction, while getting further breakthroughs, also provide a technical reference for the construction of arch bridges
