Updated September 24, 2025- The Huajiang Grand Canyon Bridge in southwest China’s Guizhou Province will become the world’s tallest bridge and will open to traffic on Sept. 28. This opening comes after more than three years of construction. This was revealed by the local government on Wednesday.
The bridge has achieved multiple technological breakthroughs in its wind-resistance design and high-altitude construction. It has obtained 21 authorized patents. Most of its technical achievements have been incorporated into national bridge construction standards, said Zhang Yin who is the head of the provincial transport department.
Guizhou boasts over 32,000 bridges that have been completed or are under construction. These bridges include the world’s three tallest. Furthemore, it is interesting to note that nearly half of the 100 highest bridges in the world are located in the province.
Updated August 2026, 2025: The world’s tallest Huajiang Grand Canyon Bridge has successfully passed a crucial load test ahead of its scheduled opening this year. The statistical load test was one that was to last from August 21 to the 25th before opening to traffic. The bridge was tested using 96 trucks each weighing 35 tonnes as they were driven onto the bridge in stages. Through this assessment, the total load that the bridge managed to handle weighed about 3,360 tonnes. The grand infrastructure stretches across the karst mountains of Guizhou Province in southwest China. The scheduled load test was considered the final step before the bridge is opened to the public.
The Huajiang grand canyon bridge over the Beipanjiang River in Guizhou Province, China, is about to finish closure in latest update. This is according to a press release by the State Council of The People’s Republic of China.
Length of the Bridge
The 2,980-meter long bridge will be the highest in the world, sitting at an height of 625 meters from the river below. The bridge will be operational by June 2025. The Huajiang grand canyon bridge in China will surpass current holder of the record, the four-lane cable-stayed Duge Bridge also in China. A rather interesting fact is that both holders of the “highest bridge in the world” record cross the same river just 200km part. The construction that kicked off in 2022 has so far seen tremendous progress that still falls within the schedule stipulated by the developers earlier on. A milestone that is calling for the bridge’s closure is the assembly and installation of 93 sections of the bridge serving the Liuzhi-Anlong expressway.

How the bridge will serve China
The Huajiang grand canyon bridge is expected to surprisingly cut down the travel time across the Huajiang canyon by 70x. Cutting down the commute time between the two bridge ends means the travel time will stand at 1 minute, down from 70 minutes. A minute of travel time across a stretch of 2,980 meters. The bridge will also boost tourism and serve as a scenic site. Anticipated activities to boost the tourism sector for Guizhou Province include sight-seeing and extreme canyon sports. The economy of the region will also see a boost as the bride will join others like the Baling River bridge in pulling resources to the province. More record breaking projects are certainly in line from the Asian powerhouse not alien to mega projects that put its name up in the global infrastructural charts.

A tremendous construction, showing both the incredible competence at Chinese construction of very high structures in moutain environments, and the wise use of international cooperation. Impressive and fitting so remarkably into the landscape….I’m not sure i wouldn’t be frightened driving over it at that height though!
