NEXCO EAST Fukushima Management Office (Fukushima City, Fukushima Prefecture) has aged reinforced concrete at the Kosugo Bridge located between the Kunimi Interchange (IC) and Shiroishi IC on the E4 Tohoku Expressway. Due to the construction to replace the floor slab with a new floor slab, the section of 2 lanes on each of the upper and lower lines will be reduced to 1 lane each, and the all-day two-way traffic regulation will be enforced from May 24 (Tuesday).
Since the number of lanes that can be driven by construction will be reduced from two lanes to one lane, traffic congestion is predicted on holidays near the construction site between Kunimi IC and Shiroishi IC on the Tohoku Expressway.
We apologize for any inconvenience caused to our customers, but when traveling in the section concerned, please make efforts for safer driving and go out with plenty of time. In addition, if you are planning to use the section on a holiday, please consider detouring to Joban Expressway, Tohoku Chuo Road, general road, changing the outing time, or using public transportation.

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. 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.
