[Construction Case] A Bridge That Doesn't Stop People or Rivers <Okouchi Bridge Replacement Project>

Bridges that do not stop the flow of people, cars, or rivers! Strong against heavy rain and earthquakes, they connect lives and revitalize communities.

We would like to introduce the construction of the "Bridge that does not stop people or rivers (Okouchi Bridge)." In the examination of the bridge type, it was determined that due to the presence of river structures in the Abe River, it was difficult to install intermediate piers. Therefore, the Nielsen-Lowes bridge, which is suitable for a span of approximately 165 meters, was selected. The Nielsen-Lowes bridge features a truss structure formed by arch members and stiffening girders supported by diagonally placed cables, providing higher rigidity compared to other types of arch bridges and allowing for longer spans. 【Bridge Overview】 ■ Type: Steel Simple Nielsen-Lowes Bridge ■ Bridge Length: 165.5m (Girders Length 164.0m) ■ Girder Height: (Arch Rise) 26.0m ■ Abutment Type: RC Inverted T-shaped Abutment ■ Foundation Type: Cast-in-place Pile Foundation *For more details, please refer to the PDF document or feel free to contact us.
