NEXCO EAST Hokkaido Regional Head Office (Atsubetsu Ward, Sapporo City) is pleased to announce the Expressway renewal work to be carried out on E5 Do-O Expressway (Dōō Expressway) from August~November 2026.
Due to the construction, lane restrictions will be implemented as follows. Please note that the number of lanes will be reduced.
Renovation work is necessary to ensure you can use Expressway safely and securely.
We will strive to minimize inconvenience to our customers, so we ask for your understanding and cooperation.

1. Location Map/Traffic Regulation Schedule

• Restrictions will also be in place all day on Saturdays, Sundays, and holidays.
• The traffic regulation period may change depending on the progress of construction.

2. Construction details

All of the construction we will inform you about this time is floor slab replacement work. In this work, the concrete floor slabs that have been damaged due to deterioration and the increase in the number of large vehicles will be replaced with new, more durable prestressed concrete slabs. In addition, high-performance floor slab waterproofing is applied to the waterproof layer to prevent deterioration of the floor slab.
