4 Construction details
About 33 years have passed since the opening of Kosakagawa Bridge located between Towada IC and Kosaka IC on the Tohoku Expressway Since concrete slabs have deteriorated and reinforced steel bars have been rusted, drastic aging work must be implemented. By replacing the deteriorated existing concrete slab with a new slab, it will be reborn as an Expressway that can be used safely and comfortably.
In addition, the Kamedayama Tunnel located in the same section has cracks on the lining surface of the tunnel, floating and peeling, etc., and it is necessary to carry out lining internal reinforcement and peeling prevention work.
This construction aims to increase the efficiency of construction work and reduce costs by carrying out slab replacement work for bridges in the restricted traffic area, tunnel repair work, and slab waterproofing work for Arakawa Bridge.
In addition, we will carry out pavement repair work, road maintenance work, and detailed road inspections.
