Onahama Marine Bridge

The Onahama Marine Bridge extends 510 meters across Onahama Port, featuring a central span of 120 meters and connecting the eastern port district with pier number three.

The bridge, inaugurated in March 2018, received the Japan Society of Civil Engineers Tanaka Prize for its innovative engineering and construction methods in maritime conditions.

The bridge name was written in traditional Japanese calligraphy by Shoko Kanazawa, a distinguished cultural ambassador of Iwaki city.

The structure includes two traffic lanes with a width of 7 meters and pedestrian paths ranging from 3 to 4.5 meters, operating with a speed limit of 40 kilometers per hour.

As Japan's first extradosed bridge in a port environment, it combines the technical advantages of both girder and cable-stayed bridge designs in maritime infrastructure.
