China to open world’s highest bridge in 2025

China’s Huajiang Grand Canyon Bridge, spanning 625 metres (2,051 feet) above the Beipan River in Guizhou Province, will become the world’s highest bridge upon completion in late 2025.

The province held the title for the world’s highest bridge twice.

Set to reduce travel time across the canyon from an hour to just one minute, the bridge will also feature a glass elevator, a stargazing bar, and the world’s highest bungee jump.

The Huajiang Grand Canyon Bridge is expected to open on June 30, 2025.
