Toyohama Bridge, Road bridge in Kure, Japan.

Toyohama Bridge is a road bridge with a steel truss structure connecting Toyoshima and Osakishimojima islands across the water. It forms part of the Akinada Tobishima Kaido route, which links multiple islands in the area through a series of bridges.

Toyohama Bridge opened in November 1992 as a farm road bridge built under Hiroshima Prefecture's Osakishimojima regional agricultural estate road project. It is the fourth of the eight bridges of the Akinada Islands connecting route, linking Toyoshima and Osakishimojima, and forms part of the Osakishimojima wide-area farm road. Its construction reused the same truss form and floating-crane methods as the earlier Kamagari Bridge.

The bridge's railings carry reliefs of the loon, Hiroshima Prefecture's bird. On the Osakishimojima side, the Toyohama Bridge Memorial Park has a 13.2 m high, 15.5 m wide jungle gym, which was described as Japan's largest; as of February 2026 it is closed because it does not meet safety standards for play equipment.

The bridge carries the Osakishimojima regional farm road, with a 5.5 m roadway and a 1.5 m walkway, and clearance for vessels below is 23.0 m. On the Osakishimojima side, the bridge memorial park has a free car park for about 20 vehicles. The park's jungle gym, 13.2 m high and 15.5 m wide, was closed to use as of February 2026 because it does not meet safety standards for play equipment.

The bridge's longest span of 240.0 m ranked ninth in Japan among truss bridges as of 2014, tied with the Kyōsui Channel Bridge and second in Hiroshima Prefecture after the Kamagari Bridge. Its steel piers use a belt-type foundation, chosen because concrete piers would have been too thick in the narrow strait beside Toyoshima fishing port.
