Bridging gap between nature and technology

Above the grand canyon of Huajiang River, which features towering cliffs and fast-flowing currents in Southwest China's Guizhou province, a steel-truss girder suspension bridge is under construction.

The main span of the bridge is 1,420 meters long. With a height of 625 meters from the bridge deck to the water's surface, the bridge is expected to become the highest in the world after its completion. It will cut travel time across the canyon from about two hours to two minutes.

The main structure of the bridge is expected to be completed by the end of 2024 and is set to be put into use in early 2025.

The 2,890-meter-long bridge is part of an expressway linking two cities in Guizhou province. Guizhou is renowned for its vast mountainous areas.

With the bridge, visiting the Huajiang Grand Canyon scenic area will also become easier. The scenic area has a planned area of 298 square kilometers, with a total length of 79 kilometers and average width of 3.8 kilometers.

As a representative of karst landscapes, Huajiang Grand Canyon is a unique canyon nicknamed the "fissure of the Earth" in China.

Working above the canyon to build the world's highest bridge is by no means an easy task, but the workers have been overcoming all difficulties to make the two ends meet.
