China Parked 96 Heavy-duty Trucks On The New ‘World’s Highest Bridge’ To Test Construction Quality

China parked 3,360 tonnes of heavy-duty trucks on the Huajiang Grand Canyon Bridge to test construction quality.

During the key load-bearing test, 96 heavy-duty trucks were driven and parked onto the bridge deck in batches to test.

Supported by two main 860 ft-tall towers, Huajiang Grand Canyon Bridge has a total length of 2.89 km and a main span of 1.42 km.

Upon completion in April 2025, the Huajiang Grand Canyon Bridge became the world’s highest bridge, measuring 2,051 feet.

It surpasses the previous highest bridge, the Beipanjiang Bridge Duge also in China, which stands 565 meters (1,854 feet) and spans 1.34 km.

The Huajiang Grand Canyon Bridge in south west China’s Guizhou Province has successfully completed its load tests, marking a key step toward its official opening to traffic at the end of September 2025.

During the last trial, ninety-six (96) heavy-duty trucks with a total of 3,360 tonnes of goods were driven and parked onto the bridge deck in batches to test the construction quality and mechanical properties of its structure.
