The Iwagi Bridge is a transportation structure connecting Iwagi Island to Seinamijima Island across waters in the Seto Inland Sea. The structure allows pedestrians and cyclists to cross, though cyclists must walk their bicycles along the entire span rather than ride.

The bridge opened on March 20, 2022, completing the Yumeshima Kaido road network that links several islands in the Kamijima region. This completion represented the final connection in a multi-year project to integrate island communities.

The bridge allows residents and visitors to move freely between island communities that were previously separated by water. It has become part of daily life for people who work, study, or socialize on multiple islands in the region.

Visitors can walk across the bridge at any time, and the route remains open year-round. Those arriving by bicycle should plan for the slower pace required to push their bikes along the entire crossing.

The bridge operates as part of a rare island connection system without traffic lights or tunnels. This straightforward design approach preserves the natural landscape while keeping travel between islands simple and direct.
