The Huajiang Grand Canyon Bridge, currently under construction in Guizhou Province, China, is set to become the world’s tallest bridge upon its completion in 2025. Spanning 2,890 meters in length and rising 625 meters above the Beipanjiang River, the bridge will surpass the Beipanjiang Bridge, which stands at 565 meters, to claim the title of the highest bridge globally.

Construction of the bridge began in January 2022, with the main span completed earlier this year. The project has faced numerous engineering challenges, including strong winds and complex mountainous terrain. To address these issues, engineers employed high-strength concrete and steel truss girders to enhance stability and reduce wind resistance.

In August 2025, a critical load test was successfully conducted, involving 96 heavy trucks totaling 3,300 tonnes. Over 400 sensors monitored the bridge’s structural response, confirming that it meets safety standards and is ready for traffic. The bridge is expected to open in late September 2025, significantly reducing travel time across the canyon from approximately two hours to just two minutes.

Beyond its transportation benefits, the Huajiang Grand Canyon Bridge is poised to become a major tourist attraction. Plans include a glass sightseeing elevator, a bar atop the bridge tower, a restaurant within the bridge structure, and extreme sports activities such as bungee jumping and climbing. These developments aim to boost the local economy by attracting tourists and fostering regional development.

The completion of the Huajiang Grand Canyon Bridge underscores China’s commitment to advancing infrastructure in challenging terrains. Once operational, the bridge will not only enhance regional connectivity but also serve as a testament to China’s engineering prowess and its ability to transform isolated regions into hubs of economic activity.
