The Akashi Kaikyō Bridge is a suspension bridge, which links the city of Kobe on the Japanese mainland of Honshu to Iwaya on Awaji Island. It crosses the busy Akashi Strait (Akashi Kaikyō in Japanese) as part of the Honshu–Shikoku Highway.

It was completed in 1998, and has the longest central span of any suspension bridge in the world, at 1,991 metres (6,532 ft; 1.237 mi). It is one of the key links of the Honshū–Shikoku Bridge Project, which created three routes across the Inland Sea.

The bridge has three spans. The central span is 1,991 m (6,532 ft; 1.237 mi), and the two other sections are each 960 m (3,150 ft; 0.60 mi). The bridge is 3,911 m (12,831 ft; 2.430 mi) long overall. 


The two towers were originally 1,990 m (6,530 ft; 1.24 mi) apart, but the Great Hanshin earthquake on January 17, 1995, moved the towers so much that the span had to be increased by 1 m (3.3 ft).
