China Built the World’s Highest Bridge 626 Meters Above the River

Imagine driving on a highway more than 600 meters above a river. The Huajiang Grand Canyon Bridge in southwestern China rises 626.01 meters above the river, making it the world’s highest bridge. But building a highway at this height required far more than simply connecting two mountains. In this documentary, we explore how engineers built one of the most extraordinary bridges on Earth—from foundations carved into steep mountain terrain to massive towers, suspension cables, and a 1,420-meter main span. We’ll also look at the Beipanjiang Bridge, the structure that previously held the record, and discover why Guizhou has become one of the world’s most remarkable centers of high-altitude bridge engineering. How do you build a highway when the ground is hundreds of meters below you? Find out how China built a road across one of the deepest mountain landscapes on Earth. ⏱️ CHAPTERS: 00:00 — The World's Highest Bridge 00:50 — Why Guizhou Needed Giant Bridges 01:35 — The Mountains That Made Bridges Necessary 03:10 — The Bridge That Held the Record 04:55 — Designing a Bridge 626 Meters Above the River 06:11 — Building Foundations on the Mountain 07:26 — Building Towers Into the Sky 08:26 — How Do You Put a Cable Across a 1,420-Meter Gap? 09:38 — The Moment the Highway Finally Connected 10:36 — A Canyon Becomes a Highway This video explores bridge engineering, Chinese infrastructure, mega projects, suspension bridges, highway engineering, and some of the most ambitious construction projects in the world.
