World's tallest bridge opens to traffic in China

29-09-2025

The world's tallest bridge opened to traffic on Sunday in southwest China's Guizhou Province, slashing travel time across a deep canyon from two hours to just two minutes after three years of construction.

The Huajiang Grand Canyon Bridge, soaring 625 m above the Beipan River in Guizhou's mountainous terrain, is nearly nine times the height of San Francisco's Golden Gate Bridge, said a Xinhua news agency report.

Spanning the Huajiang Grand Canyon, dubbed "the Earth's crack," the 2,890-m-long structure is the latest addition to the rapidly expanding infrastructure network of the world's second-largest economy.

This mega-project has attracted worldwide attention since its launch in 2022. Now, it has not only added a new landmark to Guizhou, renowned as "the world's bridge museum," but also presented the globe with a Chinese approach for building bridges in mountainous canyons.

Guizhou, the only province in China without a single plain and home to deep ravines, has long relied on tunnels and bridges to overcome its jagged karst landscape.

Today, Chinese engineers have managed to break a number of world records in the space of just three years -- not just in terms of height, but also in span. With a main span of 1,420 m, the Huajiang project has become the world's longest-span steel truss girder suspension bridge located in mountainous terrain, Guizhou provincial authorities said.
