[Construction Case] General Prefectural Road Okeo Tokuda Line (Tentative Name) Tokuda Bridge Superstructure Construction
Safety is important, scenery is important, connecting lives! A crane is moving along the bridge to sequentially install it.
The "Tokuda Bridge" was constructed in 1962 and has significantly deteriorated, with repeated traffic restrictions due to repair work, as well as a narrow road that makes it difficult for vehicles to pass each other and poor alignment leading to frequent traffic accidents. The new bridge will have a roadway that is 2 meters wider, with sidewalks on both sides, alleviating the feeling of constriction and allowing everyone to pass safely. Additionally, by eliminating traffic restrictions caused by traffic accidents and rising river levels, it is expected to be used as a vital route for the Morioka metropolitan area. 【Overview】 ■ Bridge Type: Steel 6-span continuous composite narrow box girder bridge ■ Bridge Length: 365.00m ■ Girder Length: 363.90m ■ Live Load: B live load, crowd load ■ Corrosion Protection Method: Weather-resistant steel (Friction joint surface: Coated with inorganic zinc-rich paint) *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Features】 ■ By moving the crane along the bridge and sequentially erecting it, the bridge can be constructed in a short time without obstructing the river. ■ To streamline the entire bridge, it is designed as a continuous composite bridge, utilizing precast PC slabs in the central part of the bridge span and cast-in-place PC slabs at the intermediate supports. ■ The precast PC slabs are manufactured in the factory as precast components divided along the bridge axis and are assembled and connected on-site, allowing for a reduction in on-site construction time. *For more details, please refer to the PDF document or feel free to contact us.
