September 28, 2025 11:55 am
The Huajiang Grand Canyon Bridge in southwest China’s Guizhou Province will open today (28), officially becoming the tallest bridge in the world.
Stretching 2,890 meters in length with a main span of 1,420 meters, the Huajiang Grand Canyon Bridge rises 625 meters above the river, setting a new global record.
It is not only the tallest bridge on earth but also the world’s largest span bridge ever built in a mountainous area.
Construction began in early 2022, with engineers and workers confronting the steep natural barrier of the Huajiang Grand Canyon. To achieve millimeter-level precision at an altitude of 600 meters, the project employed advanced methods including drone technology, intelligent monitoring systems, and ultra-high-strength building materials.
The completion of the bridge marks a major milestone for infrastructure development in China’s mountainous southwest, boosting connectivity and showcasing the country’s engineering capabilities.
