Hamada Marine Bridge, Coastal bridge in Hamada, Japan.

The Hamada Marine Bridge is a cable-stayed road bridge over Hamada Fishing Port in Shimane Prefecture, linking the Harai and Setogashima districts. It has a total length of 615 metres, including a 310-metre approach span, and a main tower 89 metres high (92 metres above sea level).

The Hamada Marine Bridge opened in 1999, linking the Harai district of Hamada with the Setogashima district across Hamada fishing port. Its 615-metre span, of which 310 metres are approach spans, made it the longest cable-stayed bridge among fishing port facilities in Japan.

The bridge is a daily passageway for local residents connecting Hamada to surrounding villages and shaping the rhythm of coastal life. People use it as a reference point when navigating the waters of the Sea of Japan or visiting the city.

The best time to cross is during daylight hours when visibility is clear and traffic remains predictable. Both pedestrians and drivers should prepare for changing weather conditions, as the open-water location can bring sudden wind gusts and rain.

At 615 metres, it is the longest cable-stayed bridge among fishing port facilities in Japan; the main tower rises 89 metres above the water, or 92 metres above sea level. It links the Harai and Setogashima districts of Hamada Fishing Port.
