1. 1. Construction section

Sasson Expressway Asari IC-Zenibako IC near Kamui Bridge (about 3.7km)

2. Construction / traffic regulation period

• The regulation time of "all day face-to-face traffic regulation, all day lane regulation" is 24 hours all day traffic regulation.
• The lane regulation time is from sunrise to sunset.
• All day restrictions will be applied on Saturdays, Sundays and public holidays.
• The construction period may change depending on the weather, work progress, etc.

3. Traffic restrictions

For floor slab replacement work, we will reduce the number of two lanes on each of the upper and lower lines to one lane, and implement all-day two-way traffic restrictions to consolidate on one side. For a total of 6 days, the first 3 days and the last 3 days of the construction period, we will implement all-day lane restrictions on the upper and lower lanes due to lane switching work due to face-to-face traffic restrictions.

Four. Construction content

About 50 years have passed since the opening of Kamui Bridge between Sasson Expressway Asari IC and Zenibako IC, and in addition to the minute cracks that occurred due to the increase in wheel load due to the increase in size of the vehicle, in the winter period Since the concrete floor slab has deteriorated and the reinforcing bars have rusted due to the salt contained in the antifreeze agent to be sprayed, it is necessary to replace the floor slab.
In order to replace the concrete deck part of the bridge, it is usually necessary to close the In-bound line (toward Otaru), but one lane of the Out-bound line (toward Sapporo) is used for the In-bound line (toward Otaru). By making it a two-way traffic, the construction will be carried out with the minimum impact on traffic.

By replacing the deteriorated existing concrete floor slab with a new floor slab, it will be reborn as an Expressway
