The Kurushima-Kaikyō Bridge (来島海峡大橋 Kurushima Kaikyō Ō-hashi), which connects the island of Ōshima to the main part of Shikoku, is the world's longest suspension bridge structure[1] and was completed in 1999. The bridge is part of the Shimanami Kaidō, an expressway that spans a series of islands and connects Hiroshima Prefecture in Honshū to Ehime Prefecture in Shikoku. The bridge and the expressway were both conceived by the Honshū-Shikoku Bridge Project.

The Kurushima-Kaikyō Bridge consists of three successive suspension bridges with six towers and four anchorages. There is a shared anchorage that joins each suspension bridge to the next. Its construction is similar to the western portion of San Francisco – Oakland Bay Bridge which is two successive suspension bridges with four towers and one shared anchorage. The bridge's total length of 4,015 metres (13,173 ft), is just a little longer than the total length of the two tower Akashi-Kaikyō Bridge, which is 3,911 metres (12,831 ft).
