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, was the world's longest suspension bridge structure[1] when 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.


View of the roadway

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).

  • First Kurushima Kaikyō Bridge (来島海峡第一大橋, Kurushima Kaikyō Daiichi Ō-hashi), main span 600 metres (1,969 ft), ranks 63rd largest two tower suspension bridge
  • Second Kurushima Kaikyō Bridge (来島海峡第二大橋, Kurushima Kaikyō Daini Ō-hashi), main span 1,020 metres (3,346 ft), ranks 26th largest
  • Third Kurushima Kaikyō Bridge (来島海峡第三大橋, Kurushima Kaikyō Daisan Ō-hashi), main span 1,030 metres (3,379 ft), ranks 25th largest
