The NEXCO EAST Fukushima Management Office (Fukushima City, Fukushima Prefecture) is located at E4 Tohoku Expressway 　At the Kosugo Bridge located between Kunimi Interchange (IC) and Shiroishi IC, in order to replace the aging reinforced concrete slabs with new slabs, the section of the upper and lower lanes will be reduced to one lane each, the all-day lane restriction will start from October 11 (Tuesday), and the all-day face-to-face traffic restriction will be implemented from October 18 (Tuesday), consolidating on one side.
Since the number of lanes that can be driven will be reduced from two lanes to one lane due to the construction, traffic congestion is predicted on holidays near the construction site between Kunimi IC and Shiraishi IC in Tohoku Expressway.
We apologize for any inconvenience this may cause you, but when driving on this section, please make further efforts to drive safely and leave with plenty of time to spare. In addition, customers who plan to use the relevant section on holidays should consider detouring to Joban Expressway, Tohoku Chuo Expressway, and general roads, changing the time of going out, or using public transportation.
Renewal work is necessary for the safe and secure use of Expressway. We will make efforts to minimize inconvenience to customers, so we ask for your understanding and cooperation.

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

Approximately 47 years have passed since the opening of the Kosugo Bridge between the Kunimi IC and Shiroishi IC on the Tohoku Expressway. As a result, the concrete deck has deteriorated and the reinforcing bars have rusted, so 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. Face-to-face traffic will be restricted throughout the construction section for approximately 2.4 km.

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

[Use of precast products to shorten construction period and improve quality]
By adopting precast PC floor slabs, the construction period is shortened and the regulation period is shortened.

• Precast means to manufacture a product in advance in a factory, etc.

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