Tohoku Regional Head Office Morioka management office

NEXCO EAST Morioka Management Office (Morioka City, Iwate Prefecture) is located on the E4 Tohoku Expressway between the Morioka Minami Interchange (IC) and the Morioka IC. In order to replace the aging reinforced concrete floor slab with a new floor slab, the section of each of the two lanes on the upper and lower lines will be reduced to one lane each, and all-day face-to-face traffic restrictions will be restricted to one side from Tuesday, March 22. I will carry it out.
We apologize for any inconvenience caused to our customers, but if you drive on the section, please try to drive more safely and leave with plenty of time.
Renewal work is necessary to use the Expressway safely and securely. We will do our best to minimize the inconvenience to our customers, so we ask for your understanding and cooperation.

3. Traffic restrictions

For floor slab replacement work, we will reduce the section of each of the two lanes on the upper and lower lanes to one lane, consolidate it on one side, and implement face-to-face traffic restrictions throughout the day. During the first and last few days of the construction period, lane restrictions will be applied to both the upper and lower lanes as a preparatory work for switching lanes.

Four. Construction content

Approximately 45 years have passed since the opening of the Kazuma dam bridge between Morioka Minami IC and Morioka IC on the Tohoku Expressway. Since the concrete floor slab has deteriorated and the reinforcing bars have rusted due to salt, etc., it is necessary to carry out drastic anti-aging work.
By replacing the deteriorated existing concrete deck with a new deck, it will be reborn as a safe and comfortable Expressway.

Five. Request when using

  1. The construction section will be restricted to face-to-face traffic throughout the day for approximately 2km. We do not anticipate traffic jams, but if you use the section, please try to drive safely and leave plenty of time when using it.
  2. Since the driving lane and shoulders are narrow in the two-way traffic restricted section, please observe the regulated speed when driving, secure the inter-vehicle distance, 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. 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.

6. Efforts to minimize inconvenience to customers due to construction work

[Adoption of precast products for the purpose of shortening the construction period and improving quality]
By adopting a precast PC floor slab, the construction period is shortened and the regulation period is shortened.
* What is precasting? Pre-manufacturing products at factories, etc.

[Advance notice of construction regulations and traffic jam information by construction website, signboard, etc.]
We will inform you in advance of the regulation contents by means of the construction website, signboards, banners, etc.
