[Construction Case] Bridge Connecting Time: Dojima Ohashi Improvement Project

I am working with a sense of mission to pass on the value of history to my children and grandchildren!

The "Dojima Ohashi" is a lower arch bridge with Italian Romanesque style bridge piers that was completed in 1927 (Showa 2). Ninety years have passed since its completion, and significant deterioration has occurred. Additionally, due to years of ground subsidence, the space under the girders has become lower, hindering navigation. As a result of inspections and diagnostics, a full-scale renovation project has been initiated. The project aims to extend the lifespan of the bridge and secure navigational space, while preserving the relatively sound lower bridge piers and upper arch components to maintain its historical and cultural value. The deck and flooring are being completely replaced. 【Construction Details】 ■ The upper structure will have all components removed and replaced except for the arch elements, and the passage will be secured by switching it according to the progress of the construction. ■ To carry out the work while ensuring navigational space, the waterway will be divided into two sections on the right and left banks, and the navigation route will be adjusted according to the construction site. *For more details, please refer to the PDF document or feel free to contact us.
