China to open world’s tallest bridge this week

Local officials announced on Wednesday that the Huajiang Grand Canyon Bridge in China’s Guizhou province will open on September 28, completing over three years of construction work.

Authorities confirmed that the bridge will become the world’s highest, standing 625 meters above the river. The bridge stretches 2,890 meters with a main span of 1,420 meters, making it not only the tallest but also the largest-span bridge ever built in a mountainous area. Officials say the project highlights China’s engineering strength and global leadership in bridge construction.

According to Zhang Yin, head of the provincial transport department, the project introduced several innovations in wind resistance and high-altitude construction. Engineers secured 21 patents during its development, and some of the new techniques have already been added to national bridge-building standards.

Guizhou has earned a reputation as a world hub for bridge engineering. The province has built or is constructing more than 32,000 bridges, including three of the world’s highest. Remarkably, nearly half of the top 100 tallest bridges across the globe are located in this region. The Huajiang Grand Canyon Bridge is expected to boost connectivity across the mountainous province, cutting travel times and improving local transportation networks. Authorities also believe it will attract tourism and investment, further strengthening the province’s economic growth. The upcoming launch reflects China’s continued focus on mega infrastructure projects that combine modern design, safety features, and innovation.

With this new milestone, Guizhou once again showcases its global leadership in high-altitude bridge construction, reinforcing its position at the heart of the world’s most advanced bridge engineering projects.
