4 Construction overview

About 35 years have passed since the opening of the Chitosegawa Bridge between the Ebetsu West IC and the Ebetsu East IC in 1983 (Showa 58), and the small cracks and cracks caused by the increase in wheel load due to the increase in size of the vehicle Since the deterioration of concrete floor slabs and the rust on the reinforcing bars have been caused by the salt content etc. caused by spraying the anti-freezing agent in the winter, it is necessary to replace the floor slabs.

In order to replace the concrete slab part of the bridge, it is necessary to close the Out-bound line (for Asahikawa), but one of the 2 lanes for the In-bound line (for Sapporo) should be closed for the Out-bound line (for Asahikawa). By carrying out transfer and face-to-face traffic, construction will be carried out with minimal impact on traffic.

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.
