A significant achievement has been reached in the construction of the Tianmen Grand Bridge on the Anshun-Panzhou Expressway in Guizhou. The first steel truss segment, measuring 13.6 meters in length, 36 meters in width, 6.5 meters in height, and weighing approximately 241.8 tons, has been successfully hoisted into position on the Anshun side using precise cable crane technology.

The project was carried out by China Railway Guangzhou Engineering Group Co., Ltd. under China Railway Engineering Co., Ltd.
Spanning 1,553 meters across the Beipanjiang Grand Canyon, the Tianmen Grand Bridge features a single-span steel truss suspension design with a main span of 820 meters. It is one of the most technically challenging components of the entire Anshun-Panzhou Expressway. The bridge’s main tower rises nearly 200 meters high and adopts a reinforced concrete portal frame structure. With a vertical clearance of 560 meters from the bridge deck to the river below, it is the third highest bridge in the world and the highest steel truss suspension bridge with a dual six-lane carriageway.

The Anshun-Panzhou Expressway is a key part of China’s national expressway network, with a total length of 173.02 kilometers. Upon completion, it will help alleviate traffic pressure on the Shanghai–Ruili corridor, enhance the corridor’s overall transport capacity, and play a significant role in unlocking local tourism potential and promoting the economic development of towns along the route.
