China’s Huajiang Grand Canyon Bridge in Guizhou province has successfully passed its final safety and load tests, positioning it to become the tallest bridge in the world. Rising 625 meters (about 2,050 feet) above the Beipan River, it will soon overtake all existing bridges in height and impact regional travel dramatically.
During testing, engineers used 96 heavy trucks weighing over 3,300 tonnes in total to evaluate the bridge’s strength. Equipped with more than 400 sensors, the structure was monitored for displacement and stress across towers, cables, and suspenders. The bridge passed every benchmark, clearing the way for its opening in September 2025.
The bridge stretches nearly 2,890 meters with a central suspension span of 1,420 meters, making it one of the longest suspension bridges in mountainous terrain. Constructed with 93 massive steel truss sections weighing 22,000 tonnes, it will cut travel time across the canyon from about 70 minutes to just over a minute—revolutionizing transport in the region.
Beyond transportation, the project is also expected to become a major tourist attraction. Plans include glass walkways, bungee jumping platforms, paragliding stations, and rope swings, drawing thrill-seekers and travelers from across the globe.
This landmark project showcases China’s engineering capabilities and its ambition to connect remote regions with world-class infrastructure.
