On January 17, the final steel truss girder weighing approximately 215 tons was smoothly and precisely installed using China’s independently developed fourth-generation intelligent cable crane system. The Huajiang Canyon Bridge, the world’s tallest bridge co-constructed by China Railway Hi-Tech Industry under CREC, was successfully completed.
The bridge is a key control project on the Liuzhi-Anlong Expressway and officially began construction on January 18, 2022. The main structure is a 1,420-meter-span steel truss stiffened suspension bridge, with a vertical distance of 625 meters between the bridge deck and the water surface, comparable to the height of Shanghai Tower, China’s tallest building.
Upon completion, the bridge surpasses the Beipanjiang Bridge on the Hangzhou-Ruili Expressway to become the tallest bridge in the world and the longest-spanning mountain bridge globally. The steel truss girder structure, manufactured by China Railway Hi-Tech Industry, consists of main trusses, main cross trusses, lower chords, and deck panels. It comprises 93 installation segments with a total weight of approximately 22,000 tons, equivalent to three Eiffel Towers.
