Ōta River Bridge

The Ōta River Bridge extends 412 meters across the waterway with a main span of 116 meters and a width ranging from 12.5 to 16.2 meters.

The construction project started in 2004 when local authorities approved the bridge as part of the Hiroshima Expressway system, leading to completion in March 2014.

The bridge design by Kenichi Nishiyama from Eight-Japan Engineering Consultants emerged as the winner of an international competition held in 2008.

The structure carries Route 3 of the Hiroshima Expressway while maintaining a clearance of 12 meters beneath to accommodate river navigation requirements.

The bridge combines a prestressed concrete continuous rigid frame box girder with a steel arch bridge stiffener, earning recognition from the Japan Society of Civil Engineers.
