Top 10 Longest Suspension Bridges in the World
Suspension bridges are marvels of engineering that combine aesthetic elegance with incredible structural efficiency. Even so, the following list ranks the ten longest suspension bridges worldwide, measured by the length of their main span (the distance between the two towers). In practice, by suspending the deck from massive cables anchored at each end, these bridges can span distances that would be impossible for beam or arch designs. Each entry highlights the bridge’s location, year of completion, key dimensions, and a brief note on its significance Easy to understand, harder to ignore. Still holds up..
Introduction
When engineers talk about “longest suspension bridge,” they refer to the main span—the uninterrupted section of the deck that hangs between the two primary towers. Think about it: this metric isolates the pure spanning capability of the suspension system, excluding approaches and anchorages. The bridges below represent the cutting edge of cable‑stayed technology, materials science, and construction logistics, often built to connect densely populated regions, make easier international trade, or overcome formidable natural barriers such as wide rivers, deep valleys, or busy shipping lanes.
Overview of the Ranking Criteria
- Main Span Length: The primary figure used for ranking (in meters and feet).
- Total Length: Includes approaches; provided for context but not the ranking basis.
- Location & Crossing: Geographic setting and what the bridge spans (river, strait, bay).
- Year Opened: Indicates the era of technological advancement.
- Notable Features: Unique design elements, record‑holding attributes, or cultural importance.

- Main Span: 1,550 m (5,085 ft)
- Total Length: 2,682 m (8,799 ft)
- Crossing: Gulf of İzmit, part of the Istanbul‑Izmir highway
- Opened: 2016
- Highlights: One of the longest suspension bridges in Europe, it shortened travel time between Istanbul and İzmir by over an hour.
5. Jiashao Bridge – China
- Main Span: 1,380 m (4,527 ft)
- Total Length: 2,940 m (9,645 ft)
- Crossing: Qiantang River, linking Jiaxing and Shaoxing in Zhejiang Province
- Opened: 2013
- Highlights: Its twin‑tower design uses high‑strength steel cables, allowing a slender profile that blends with the river’s scenic landscape.
6. Runyang Yangtze River Bridge (South Bridge) – China
- Main Span: 1,490 m (4,888 ft) – Note: The north bridge is a cable‑stayed span; the south bridge is suspension.
- Total Length: 3,566 m (11,699 ft)
- Crossing: Yangtze River, Jiangsu Province
- Opened: 2005
- Highlights: Part of a massive crossing complex that includes a cable‑stayed bridge and several viaducts, forming a key artery on the Beijing‑Shanghai railway corridor.
7. Humber Bridge – United Kingdom
