NEXCO EAST Hokkaido Regional Head Office (Atsubetsu-ku, Sapporo City) is pleased to inform you about Expressway renewal construction work to be carried out on the E5 Do-O Expressway and the E5A Sasson Expressway from May to August 2024 Lane restrictions will be implemented as follows. Please note that the number of lanes will be reduced.
The renewal work is necessary to ensure that customers can use Expressway safely and securely. We will do our best to minimize the inconvenience to our customers, so we ask for your understanding and cooperation.

1. Location Map/Traffic Regulation Schedule

• Saturday, Sunday and public holidays are also regulated all day.
• The traffic regulation period may change depending on the progress of construction.
• Please check the latest traffic information before departure, as actual traffic conditions may differ from forecasts due to accidents, weather, etc.

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.

3. Requests when using

1. The construction section will have lane restrictions throughout the day. We do not anticipate traffic jams, but congestion is expected in the mornings, evenings, and on holidays, so please allow yourself plenty of time to get out.
2. Since the lanes and road shoulders are narrow, please observe the speed limit when driving, secure a distance between vehicles, and be careful of rear-end collisions. In addition, lanes will change significantly before and after the restricted section, so please follow the local guidance signs.
3. Vehicles for construction work may enter and leave the area around the construction site, so please be careful when traveling ahead.
4. During the construction period, we will provide traffic congestion information using LED information boards, provide construction regulation information using road information boards and road signs, and call attention to driving safely. Please check this information before driving and drive safely.
