Onomichi Bridge

Onomichi Bridge is a cable-stayed road bridge that connects the Honshu mainland with Mukaishima Island across the Seto Inland Sea. The structure uses steel cables strung from tall concrete towers to support the roadway for both vehicles and bicycles.

The bridge opened in 1968 and created the first permanent link between Honshu and Mukaishima Island. Its completion transformed regional transportation and island accessibility.

Engineers recognize the bridge's technical excellence through the Japan Society of Civil Engineers Tanaka Prize, reflecting Japanese expertise in infrastructure development.

The crossing has a dedicated bicycle path for riders on the Shimanami Kaido cycling route, with bike rentals available at both entry points. Plan your visit during clear weather for the best views across the water.

The bridge forms part of the Nishiseto Expressway system, which connects multiple islands through nine bridges between Honshu and Shikoku.
