2. Construction details

The construction works we are announcing today are all deck replacement works. In these works, we will replace the concrete decks that have been damaged due to aging and an increase in large vehicles with new, more durable prestressed concrete decks. In addition, we will also implement high-performance deck waterproofing to the waterproof layer to prevent deterioration of the decks.

3. Requests when using

  1. Traffic congestion is predicted to occur in some sections of the construction zone, so please allow plenty of time for your trip.
  2. As the driving lanes and road shoulders are narrow, please observe the speed limit when passing, maintain a safe following distance, and be careful to avoid rear-end collisions. In addition, the lanes change significantly before and after the restricted section, so please follow the local information 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 information using LED information boards, construction restriction information using road information boards and road signs, and will be calling for caution so that people can pass safely. Please check this information when passing through and pass through safely.

Four. Requests when passing special vehicles

Due to regulations related to this construction, special vehicles over 3.0m in width will not be allowed to pass. For those using the service, please take a detour to nearby roads.
Also, please note that if special vehicle traffic permission (*) has been obtained only for Expressway routes, you will also need to obtain permission for general roads.

  • What is special vehicle passage permission?
    Based on the Road Law and the Vehicle Restriction Ordinance, this is a permit required for special vehicles that exceed general restrictions (length, weight, vehicle width, etc.) to pass on public roads.
