The Ōta River Bridge ( Japanese: 太田川大橋, also rendered in rōmaji as Otagawaohashi, also called Otagawa Bridge or Otagawa Ohashi Bridge) is a bridge on the Ōta River in Hiroshima, Japan. It is the southernmost of all the crossings of the Ōta River and carries Route 3 (the Hiroshima Minami Route) of the Hiroshima Expressway.
A decision to build a bridge as part of the expressway system was made in 2004. [3]: 3 A design competition committee was formed in late 2008 and received entries from 18 Japanese and three international firms. The winning design by Kenichi Nishiyama of Eight-Japan Engineering Consultants collaborating with Yoko Kabaki, Akiyoshi Nii, and Hitoshi Okamura, was selected in July, 2009. [4] [5]
The bridge was built by Shimizu Corporation and finished in 2014. [6] The bridge design had to comply with height restriction laws due to its proximity to Hiroshima–Nishi Airport. [2]
The bridge, a composite prestressed concrete continuous rigid frame box girder with steel arch bridge stiffener, [2] won the Japan Society of Civil Engineers Tanaka Award. [7]
