4 Construction details

Miyagi Shiraishigawa Bridge, located between the Tohoku Expressway Kunimi IC and Shiroishi IC (up and down line), has been around for 43 years since its opening. The deterioration of concrete slabs and the rust of steel bars have occurred due to the salt content of the agent spraying, so it is necessary to implement drastic aging countermeasures.

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.
