The tallest bridge in the world was opened to traffic in China on Sunday 28 September 2025, crowning - state media report - a three-year engineering feat and snatching the record from another bridge in the same province.

The Huajiang Grand Canyon Bridge is 625 metres high and spans a river and a vast gorge in the southern province of Guizhou, which is also home to the 565-metre-high Beipanjiang Bridge, now the second highest in the world.

Crowds of onlookers, including project engineers and local officials, gathered on the bridge for a ceremony to mark the occasion, and many expressed their pride and enthusiasm in live interviews with state media.

'The opening of the Huajiang Grand Canyon bridge reduces travel time between the two banks from two hours to two minutes,' said Zhang Yin, head of the provincial transport department, at a press conference.

Its opening up brings 'huge improvements to regional transport conditions and promotes regional economic and social development', he said. China has invested heavily in major infrastructure projects in recent decades, a period of rapid economic growth and urbanisation in the country.

The hilly province of Guizhou, in particular, is criss-crossed by thousands of bridges, which now include the two tallest in the world. According to the state-run Xinhua news agency, almost half of the 100 tallest bridges in the world are located in the province.

Its main span of 1,420 metres makes it 'the world's largest span bridge built in a mountainous area', Xinhua reported. Apart from the world's tallest bridge, the tallest - measured in terms of the height of its structure, rather than distance from the ground - remains the French Millau Viaduct, at 343 metres.
