Cross the Golden Gate and Sydney Harbour. China is set to open the world’s tallest bridge in June, the latest feat of engineering from the infrastructure-focused country.
The Huajiang Grand Canyon Bridge in southwest China’s Guizhou is nearing completion. It will stand 2,051 feet above river level, 947 feet higher than the current bridge title holder, the Millau Viaduct in France.
Guizhou province is a mountainous region in China with a complex terrain. The bridge spans the dramatic Huajiang Grand Canyon, also known as the “Cleft of the Earth.”
China has a nationwide push to improve infrastructure, especially in relatively underdeveloped mountainous regions like Guizhou, 800 miles west of Shenzhen.
So the bridge isn’t just a record-breaker — once it’s up and running, it will make it easier than ever for cars and trucks to travel through the area. It will cut travel time across the Huajiang Grand Canyon from two hours to one minute, according to state media.
The bridge is a steel truss suspension bridge with a total length of 9,482 feet. Construction officially began on January 18, 2022, and is expected to be completed on June 30, 2025, according to Guizhou regional state media.
In total, the trusses weigh about 22,000 tons, the same as three Eiffel Towers.
“Currently, the overall progress of the bridge has reached 95%, and it is planned to open to traffic in the second half of 2025,” Zhang Zhenglin, chief engineer of Guizhou Expressway Group, told the state-run China Daily.
“By then, this super project, which spans the “earth crack”, will be the first in the world on both sides. It will become another landmark project that demonstrates China’s infrastructure strength,” Zhang added.
Currently, about half of the world’s 100 tallest bridges are located in Guizhou.
