4 Construction details

About 35 years have passed since the opening of the Riko Nogibashi, which is located between the Ikarugaseki IC and the Owani Hirosaki IC on the Tohoku Expressway Due to salt, etc., concrete floor slabs have deteriorated and reinforcing bars have rusted, so it is necessary to implement drastic measures against deterioration.

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.
