GUIYANG, Sept. 19 (Xinhua) --With a designed deck height of 625 meters, the Huajiang Grand Canyon Bridge is set to be the highest in the world upon its completion in 2025.

The 2,890-meter-long bridge is located in Bouyei-Miao Autonomous County of Guanling and is part of an expressway linking the Liuzhi special district of Liupanshui City and Anlong County of Bouyei-Miao Autonomous Prefecture of Qianxinan, Guizhou Province.

The last main tower of the bridge was completed on Oct. 24 of 2023. And the main cables of the bridge have been set completely in recent days since its construction began on April 9, 2024.

With a designed construction period of 42 months and a total cost of two billion yuan (about 280 million U.S. dollars), the bridge will become the world's highest one, surpassing the Beipanjiang Bridge, after its completion.
