4 Construction details

About 40 years have passed since the opening of the Omorigawa Bridge and Matsuzukagawa Bridge between the Tohoku Expressway Nihonmatsu IC and Fukushima Iizaka IC (upper and lower lines). Since the salt content of the anti-freezing agent sprayed on causes the deterioration of concrete floor slabs and rust on the reinforcing bars, 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.
