Kamagari Bridge, Road bridge in Kure, Japan

Kamagari Bridge is a 480-metre road bridge over the Sannose Strait between Shimokamagarijima and Kamikamagarijima in Kure, Hiroshima Prefecture. It is a three-span continuous steel truss with a curved lower chord, a maximum span of 255 metres, a roadway of 6.5 metres and a 1.5-metre walkway, standing 23 metres above the sea.

The bridge opened in October 1979 and marked a turning point for transportation in the Hiroshima region. This opening fundamentally changed how the islands connected to each other.

The bridge connects island communities that rely on regular contact for daily commerce and social life, making it essential infrastructure for people living on both sides of the strait.

The bridge is open to vehicle traffic year-round and undergoes regular inspections to maintain its structural condition. Visitors should expect normal traffic conditions and be aware that heavy vehicle flow can occur during peak times.

The bridge's 255-metre main span made it Japan's longest farm-road bridge when it opened in 1979, and in 2014 it was still the country's seventh-longest truss span and Hiroshima Prefecture's largest truss bridge. Builder Ishikawajima-Harima Heavy Industries erected the truss by floating crane as a single large block, the first such lift for a truss bridge.
