New Delhi, 27 August 2025: China’s Huajiang Grand Canyon Bridge, now officially the tallest bridge in the world, has successfully passed its final safety test before opening to the public. Standing an incredible 625 meters above the canyon floor, the bridge is being celebrated as an “unprecedented engineering feat.”

From August 21 to 25, engineers carried out a rigorous static load test to ensure the structure’s safety and stability. A total of 96 heavy trucks, weighing 3,360 metric tons, were carefully placed on the bridge in batches. More than 400 high-tech sensors monitored its towers, cables, suspenders, and main span for even the slightest movement. Experts later confirmed that the bridge’s strength, stiffness, and performance all meet international safety standards.
About the Huajiang Grand Canyon Bridge
Stretching 2,900 meters in length with a main span of 1,420 meters, the bridge towers over Guizhou Province’s stunning karst mountains. Once it opens, it will hold two world records — not only as the tallest bridge on Earth but also as the longest-span bridge ever built in a mountainous region.

Project manager Wu Zhaoming from Guizhou Transportation Investment Group Co., Ltd. explained that the construction team faced enormous challenges. These included stabilizing steep canyon slopes, dealing with extreme temperatures during large concrete pours, and overcoming the dangers of high winds. Yet, despite the odds, the project was completed ahead of schedule, marking a new milestone in China’s bridge engineering.
What It Means for the Region
The bridge, scheduled to open in September, is expected to bring a major boost to local tourism and economic development. One of its biggest advantages will be cutting travel time between Liuzhi and Anlong from nearly two hours to just two minutes.
China already dominates the global bridge rankings, with eight of the world’s ten tallest bridges located in Guizhou alone. The Huajiang Grand Canyon Bridge further strengthens that position, pushing the boundaries of engineering and redefining what’s possible in modern infrastructure.
