The bridge is part of the Shimanami Kaido, an expressway that spans a series of islands and connects Hiroshima Prefecture in Honshu to Ehime Prefecture in Shikoku. The bridge and the expressway were both conceived by the Honshu-Shikoku Bridge Project.

The Kurushima-Kaikyo 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-Kaikyo Bridge, which is 3,911 metres (12,831 ft).
