List of longest suspension bridge spans
The world's longest suspension bridges are listed according to the length of their main span (i.e., the length of suspended roadway between the bridge's towers). The length of the main span is the most common method of comparing the sizes of suspension bridges, often correlating with the height of the towers and the engineering complexity involved in designing and constructing the bridge. If one bridge has a longer span than another, it does not necessarily mean that the bridge is longer from shore to shore (or from abutment to abutment).
Suspension bridges have the longest spans of any type of bridge. Cable-stayed bridges, the next longest design, are practical for spans up to just over one kilometre (the longest cable-stayed bridge in the world has a 1,176 m span). Therefore, as of October 2025, the 28 longest bridges on this list are the 28 longest spans of all types of vehicular bridges.
The 1915 Çanakkale Bridge in Turkey holds the record since opening to traffic in March 2022, with a span of 2,023 metres (6,637 ft). Since 1998, the Akashi Kaikyo Bridge in Japan previously held the record with a span of 1,991 metres (6,532 feet).
Completed suspension bridges
This list includes only completed suspension bridges that carry automobiles or trains that are at least 1,000 m (3,300 ft) long. It does not include cable-stayed bridges, footbridges, or pipeline bridges.
Bridges under construction
Most of the large suspension bridges built in recent years have been in the People's Republic of China. As the following list shows, most of the bridges under construction are also in China.

Kurushima Kaikyō Bridge (Japan). Opened in 1999, it is the world's longest suspension bridge structure.
Great Seto Bridge (Japan). Opened in 1978 and 1988, it is the longest two-tiered bridge system (but not all of the spans that make up the bridge system are suspension bridges).
