On September 28, the world’s tallest bridge—the Huajiang Canyon Bridge on the Liuzhi–Anlong Expressway in Guizhou Province—was officially opened to traffic.
Spanning the border between Qianxinanzhou and Anshun City in Guizhou, the Huajiang Canyon Bridge has a total length of 2,890 meters and a vertical height of 625 meters from the deck to the river surface. The main bridge is a single-span steel truss suspension bridge with a span of 1,420 meters—ranking first in the world for both bridge height and span among mountain bridges. China Railway Major Bridge Engineering Group’s subsidiary Bridge Science Research Institute was responsible for construction monitoring, while China Railway Hi-Tech Industry’s subsidiary China Railway Baoji Bridge Group manufactured 22,000 tons of steel structures, including the main truss.
The Huajiang Canyon Bridge is a key control project on the Liuzhi–Anlong Expressway. Upon completion, it will greatly shorten the travel distance between Liuzhi and Anlong, further improve Guizhou’s transportation network, and inject new momentum into regional economic and social development. It will also accelerate resource integration and industrial collaboration among the Guiyang, Anshun, and Qianxinan city clusters, providing strong support for Guizhou’s integration into the New Western Land-Sea Corridor.
