en.Wedoany.com Reported - The Wumengshan Bridge on China's Naqing Expressway won the Eugene Figg Award at the 43rd International Bridge Conference (IBC) awards ceremony. Named after the late renowned bridge designer Eugene Figg, this award is the highest global honor for bridge design and construction, recognizing iconic bridge projects that are aesthetically pleasing, revolutionary, and innovative. The ceremony was held on June 15 local time in Maryland, USA. The bridge was constructed with participation from China Railway Baoji Bridge Group, a subsidiary of China Railway Industrial under China Railway.
Located at Lujiayan, Pingji Village, Zhongzhai Township, Liuzhi Special District, Liupanshui City, Guizhou Province, the Wumengshan Bridge is a key control project of the Naqing Expressway. With a main span of 270 meters, it was built to cross the Azhi River Valley and its adjacent slopes, where the maximum ground slope approaches 65 degrees. As the world's first steel truss web-concrete composite arch bridge, its design breaks through the structural limitations of traditional arch bridges, combining the lightweight nature of steel structures with the stability of concrete, enriching the types of bridge structures for spans ranging from 200 to 400 meters.
During the bridge's construction, China Railway Baoji Bridge Group was responsible for the manufacturing and on-site assembly of the entire steel structure. To meet precision control requirements for single truss panel flatness, truss height, and segment length, the project team employed meticulous ground mold lofting and full-process quality control. On-site weld joints were strictly inspected from raw material re-inspection through cutting, processing, welding, and flaw detection, achieving a first-pass flaw detection rate of 99.35%. After nearly three years of construction, the Wumengshan Bridge officially opened to traffic on September 26, 2025, playing a role in improving the backbone road network structure of Guizhou Province's highways and promoting tourism and socio-economic development in the southwestern region.
