Key Highlights
- Huajiang Grand Canyon Bridge will eclipse all previous records with a 625‑meter clearance.
- The top half of the list is dominated by Chinese bridges, underscoring the country’s engineering leap.
- Most structures are suspension or cable‑stayed, marrying aesthetic slenderness with high load capacity.
- Several bridges already serve vital expressways, boosting regional connectivity.
Detailed Insights
By 2025, China will own six of the world’s tallest bridges, many of which are critical links across rugged terrain. The following snapshots highlight each of the top ten spans and their architectural significance.
- Huajiang Grand Canyon Bridge (625 m): a suspension bridge over the Beipan River in Guizhou, scheduled to open in late September 2025.
- Duge (Beipanjiang) Bridge (565 m): a cable‑stayed structure connecting Guizhou and Yunnan, previously the world’s record holder.
- Tianmen Bridge (560 m): an 820‑meter‑span suspension bridge on the Anpan Expressway.
- Xiaowan Lancangjiang Bridge (520 m): a cable‑stayed bridge traversing the Lancang River in Yunnan.
- Siduhe Bridge (496 m): a suspension bridge over the Sidu River in Hubei.
- Lugu Lake Bridge (493 m): crossing the northern rim of Lugu Lake in Sichuan.
- Puli Bridge (485 m): a cable‑stayed span in Yunnan’s remote valleys.
- Jinshajiang Wudongde Bridge (485 m): a suspension bridge in Sichuan, part of the G5501 Expressway.
- Yalong Liangshan Bridge (480 m): a cable‑stayed bridge across the Yalong River in Sichuan.
- Nanpanjiang Bridge Puzhehei (475 m): a suspension bridge spanning the Nanpan River in Yunnan.
Key Concepts
- Bridge Height: the vertical distance from the lowest point of the bridge deck to the ground or water surface below.
- Suspension Bridge: a bridge type wherein the deck is hung below suspension cables on vertical towers.
- Cable‑Stayed Bridge: a bridge where the deck is directly supported by cables anchored to rigid pylons.
- Main Span: the longest unsupported section between two anchor points or towers.
- Clearance: the vertical distance available above the bridge for vessels or roadways below.
