Which Bridge is the Tallest in the World?

Contrary to misconception, this is neither the world’s tallest nor highest bridge.

That title belongs to China’s Huajiang Grand Canyon Bridge in Guizhou, slated to reach a deck height of 625 m—making it the world’s highest deck‑height bridge upon its mid‑2025 debut .

The tallest bridge in terms of pylon height globally remains France’s Millau Viaduct, with towers reaching 1,125 ft (343 m).
