The Akashi Kaikyo Bridge is a suspension bridge which links the city of Kobe on the Japanese island of Honshu to Iwaya on Awaji Island. It is part of the Kobe-Awaji-Naruto Expressway, and crosses the busy and turbulent Akashi Strait. It was completed in 1998, and at the time, was the longest central span of any suspension bridge in the world, at 1,991 metres (6,532 ft). Currently, it is the second-longest, behind the 1915 Çanakkale Bridge that was opened in March 2022.

A suspension bridge is a type of bridge in which the deck is hung below suspension cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world.
