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, in order to prevent deterioration of the floor slab, a high-performance floor slab waterproofing will be applied to the waterproof layer.

3. Requests when using

  1. The construction section will have lane restrictions throughout the day. We do not anticipate traffic jams, but we do anticipate congestion 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.
