Structure located in Guizhou is set to open by September, connecting regions and boosting the local economy.
The Huajiang Canyon Bridge in Guizhou Province, considered the highest in the world under construction, has undergone a series of static and dynamic load tests to assess its structural safety ahead of its scheduled inauguration at the end of September.

The procedure systematically evaluated the performance of the bridge’s four main systems: main cable and hangers, main girder, main tower, and anchor. According to the Guizhou Communications Investment Group, responsible for the project, the so-called “double test” simulated different traffic conditions and extreme loads, ensuring that the bridge can withstand daily operation without damage.

The static load tests took place on August 21, 22, 24, and 25, after adjustments due to adverse weather conditions. Convoys of 18, 48, and 96 vehicles were used, reaching a maximum load of over 3,300 tons. This simulation reproduced different scenarios of traffic flow and weight distribution.
Sensors installed at critical points monitored in real time the structural stress, deflection, displacements, cable forces, and deformations. Preliminary analysis of the data showed that the bridge responded elastically to the applied loads, with all indicators within normal ranges.
The grandeur of the project
The bridge will have a total length of 2,890 meters, with a main span of 1,420 meters. Its deck will be positioned 625 meters above the water surface, consolidating it as the highest bridge in the world.
Local authorities emphasize that the project will be vital for Guizhou’s economic development, improving connectivity between mountainous regions and accelerating the circulation of resources and people.
