China Unveils World’s Tallest Bridge, Shrinks 2-Hour Journey to 2 Minutes

China Opens Huajiang Grand Canyon Bridge, World’s Tallest, Cutting Travel Time From 2 Hours to 2 Minutes.

China’s Huajiang Grand Canyon Bridge, dubbed “the Earth’s crack,” has officially opened to traffic, offering a breathtaking engineering feat 625 metres above the Beipan River. The bridge, the world’s tallest, slashes travel time across the canyon from two hours to just two minutes.

Completed in roughly three and a half years, the bridge stretches 2,890 metres with a main span of 1,420 metres, making it the world’s tallest bridge and the largest-span bridge in a mountainous region.

Live drone footage broadcast by state media on September 28 showcased vehicles smoothly crossing the scenic bridge, highlighting both its scale and the surrounding natural beauty.

Rigorous Testing

Before opening, the bridge underwent a crucial load test on August 25, considered the final step before traffic. Engineers conducted both static and dynamic tests, driving 96 trucks weighing a total of 3,300 tons across designated points on the deck to measure displacement and stress in the main span, towers, cables, and suspenders.

Guizhou’s Engineering Boom

Guizhou, one of China’s less developed regions, has constructed more than 30,000 bridges, including three among the world’s tallest. Notably, the previous tallest bridge in the area, also crossing the Beipan River, opened in 2016, just over 100 kilometres away.

The Huajiang Grand Canyon Bridge not only demonstrates China’s engineering prowess but also promises to transform connectivity and travel efficiency in the region.
