On June 30, 2025, China will open the world’s tallest bridge, the Huajiang Grand Canyon Bridge, in Guizhou province. Soaring 2,051 feet (625 meters) above the Beipan River, it surpasses the Millau Viaduct in France by 947 feet (289 meters). Spanning the dramatic Huajiang Grand Canyon, known as the “earth crack,” the bridge is a feat of engineering amid Guizhou’s rugged terrain.
It stretches 9,482 feet (2,890 metres) in length, with a main span of 4,660 feet (1,420 metres) supported by two towers, each standing 860 feet (262 metres) tall. Designed as a steel truss suspension bridge, it was engineered to reduce environmental impact by avoiding support pillars in the canyon below.
Construction began on 18 January 2022 and is currently 95% completed. Costing approximately $280 million (€258 million), the new bridge’s 22,000-ton steel trusses are equivalent to three Eiffel Towers.
China's Huajiang Grand Canyon Bridge is set to open this year, becoming the world's tallest bridge at 2050 feet high.

China’s government has taken action across the country to improve infrastructure, specifically in underdeveloped regions such as Guizhou which is 800 miles (1,287 kilometres) west from the city of Shenzhen.
“At present, the overall progress of the bridge has reached 95%, and it is planned to be opened to traffic in the second half of 2025,” Zhang Shenglin, chief engineer of Guizhou Highway Group, told the state-run newspaper China Daily.
Moreover, once operated the bridge will help slash time travel over the canyon to one minute reported local media. By improving regional connectivity and reducing transportation costs, the bridge is expected to boost economic activity and facilitate easier movement of goods and people across the remote mountainous terrain.

While residents and businesses in Guizhou Province will be the first to benefit from the world’s tallest bridge, local officials also aim to make it a major tourist attraction. One tower will feature a glass elevator with panoramic views, along with a Stargazing Bar and Café. Visitors would be able to walk across a glass floor beneath the road deck and experience the world’s highest bungee jump.
“By then, this super project that spans the “earth crack” will be the world’s first in both directions. It will become another landmark project to demonstrate China’s infrastructure strength,” explained Zhang.
Currently, almost half of the 100 tallest bridges in the world are located in Guizhou. The completion of Huajiang Grand Canyon Bridge will mark China’s third time claiming the world’s tallest bridge title, following the Beipanjiang Guanxing Bridge in 2003 and the Duge Bridge in 2016.
