 NEXCO東日本福島管理事務所(福島県福島市)は、E4東北自動車道 国見(くにみ)インターチェンジ(IC)~白石(しろいし)IC間に位置する塩川橋、斉川橋、大平橋の3橋において、老朽化した鉄筋コンクリート床版を新しい床版に取り替える工事のため、上下線各2車線の区間を各1車線に減少させ、片側に集約する終日対面通行規制を10月4日(月)から実施します。
 工事により走行可能な車線数を2車線から1車線へ減少させることから、東北道の国見IC~白石IC間の工事箇所付近において、休日に渋滞が予測されています。
 お客さまにはご迷惑をおかけしますが、当該区間を走行される場合、更なる安全運転に努めていただきますとともに、時間に余裕をもってお出かけください。また、休日に当該区間のご利用を予定されているお客さまにおかれましては、常磐道・東北中央道や一般道への迂回、お出かけ時間の変更または公共交通機関の利用についてご検討をお願いします。
 リニューアル工事は、高速道路を安全・安心にご利用いただくために必要な工事です。お客さまへのご迷惑を最小限とするように取り組んでまいりますので、ご理解とご協力をお願いします。

3. 3. Traffic regulation contents

For the floor slab replacement work, the section of each of the two lanes on the upper and lower lanes will be reduced to one lane each, and will be consolidated on one side to implement two-way traffic restrictions throughout the day. During the first few days of the construction period, as a preparatory work for switching lanes, both the upper and lower lanes will be subject to continuous lane regulation day and night.

Four. Construction content

About 45 years have passed since the opening of the Shiokawa Bridge, Saikawa Bridge, and Ohira Bridge, which are located between the Kunimi IC and Shiraishi IC on the Tohoku Expressway Due to the salt content of the antifreeze spraying during the period, deterioration of the concrete floor slab and rust on the reinforcing bars have occurred, so it is necessary to carry out drastic anti-aging work.
By replacing the deteriorated existing concrete floor slab with a new floor slab, it will be reborn as an Expressway

Five. Request when using

  1. 工事区間は約4.1kmにわたって終日対面通行規制を行います。現状の片側2車線から1車線へ減少となり、工事箇所を先頭に、最大で5km程度の渋滞が予測されていますので、常磐道・東北中央道や一般道への迂回、お出かけ時間の変更または公共交通機関の利用についてご検討をお願いします。
  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.
* Precast is to manufacture products in advance at factories, etc.

[Advance notice of construction regulations and traffic jam information by TV commercials, radio commercials, newspaper advertisements, etc.]
We will inform you in advance of the regulation contents by TV commercials, radio commercials, newspaper advertisements, mainly in the Tohoku region.
