At around 5 p.m. on August 25, the load testing of the Huajiang Canyon Bridge concluded after 96 heavy-duty trucks with a total weight of 3,300 tons crossed the bridge. Preliminary data analysis showed that all indicators responded normally. The World’s Highest Bridge, built with the participation of China Railway Hi-Tech Industry under CREC, has thus laid a solid foundation for its scheduled opening to traffic by the end of September this year.
The load test lasted for five days. According to a combined dynamic and static testing plan, trials were carried out using 18, 48, and 96 trucks, with the maximum load exceeding 3,300 tons. These tests comprehensively evaluated the actual performance of the bridge’s four main systems: main cables and hangers, main girder, main tower, and anchor blocks.
The Huajiang Canyon Bridge is located in?Guizhou Province. The bridge has a total length of 2,890 meters, with the deck standing 625 meters above the river. Its main span is a 1,420-meter single-span steel truss suspension bridge, ranking first worldwide in both mountainous bridge span and bridge height. China Railway Baoji Bridge Group under China Railway Hi-Tech Industry undertook the production of the main trusses and other steel structures, involving 93 installation segments with a total weight of about 22,000 tons.
Upon completion, the bridge will reduce travel time across the canyon from nearly one hour to just two minutes, effectively removing a major transportation bottleneck in southwest Guizhou.
