The bridge was opened to traffic on December 24, 2020. Designed to a dual six-lane Class I highway standard, it serves as a vital channel crossing the Bagua Zhou Branch River of the Yangtze River on National Highway 104 (Nanjing Section) and is an important component of the Nanjing Ring Expressway.

     Its technical highlights include a main bridge designed as a curved single-column steel tower steel box girder cable-stayed bridge with a main span of 500 meters. The bridge features a tower height of 166 meters and a total deck width of 54.4 meters, ranking it among the widest bridges on the Yangtze River.

     The project represents a domestic and international innovation as the first of its specific bridge type. It achieved a pioneering milestone by implementing BIM-based 3D forward parametric design for large-span steel bridges, driving BIM application throughout its entire construction process and revolutionizing traditional design methodologies.
