April 7, 4th year of Reiwa
East Nippon Expressway Co., Ltd.
Niigata Regional Head Office

NEXCO EAST Niigata Regional Head Office (Chuo-ku, Niigata City) will carry out renewal work of the bridge between the E17 Kan-Etsu Expressway Shiozawa-Ishiuchi Interchange (IC) and Muikamachi IC.
The work to be carried out this time is to replace the old floor slab of Nakanoshima Bridge (Out-bound side) in the target section with a new one.
During the construction period, we will regulate one lane all day, which reduces the number of lanes to one lane on each side, and all day two-way traffic regulation, which will be operated with one lane on each side by consolidating the upper and lower lines on Nakanoshima Bridge (In-bound line side). ..
It is predicted that there will be no traffic congestion due to lane restrictions.
We apologize for the inconvenience caused to our customers, but we ask that customers using the target section be careful when driving. Renewal work is necessary for the safe and comfortable use of the Expressway, so we ask for your understanding and cooperation.

Outline of floor slab replacement work
Floor slab replacement work is the work to replace concrete floor slabs that have been damaged due to aging or the increase in large vehicles with new, more durable prestressed concrete floor slabs. In addition, high-performance floor slab waterproofing will be installed on the waterproof layer to prevent deterioration of the concrete floor slab.

6. Request when using

  1. The construction section will be restricted to face-to-face traffic throughout the day for approximately 4km. The current two lanes on each side will be reduced to one lane, so please drive more safely.
  2. Since the shoulders of the road are narrow in the two-way traffic regulation section, please observe the regulated speed when driving, secure the distance between vehicles, and be careful about rear-end collisions. In addition, the lanes will change significantly before and after the two-way traffic regulation 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. Before going out, please check the latest lane regulations and traffic information on the sites described in "8. Road Traffic Information Information". In addition, please leave plenty of time when using it.
  5. During the construction period, we will provide construction regulation information using LED information boards and road signs and call attention to driving safely. Please check this information before driving and drive safely.

7. 7. Request when passing special vehicles

Due to this regulation, from May 23 (Monday) to July 12 (Tuesday), special vehicles with a width of 3.0 m or more cannot pass between Shiozawa-Ishiuchi IC and Muikamachi IC (upper and lower lines). Customers using this service are requested to detour to National Highway No. 17.
Also, please note that if you have obtained a special vehicle permit (*) only for Expressway routes, you will also need to obtain a permit for general roads.

  • What is special vehicle passage permission?
