2 Congestion prediction

Inside the outer ring road, during the construction period During high traffic hours in the morning and evening, Due to the construction, we expect a traffic jam of up to 10km near Bijogi JCT.

In addition to the construction work, traffic congestion is expected to cause a maximum of 10km of traffic congestion at Kawaguchi Higashi IC. This is because the traffic volume on the outer ring road has increased due to the opening of the outer ring road Misato Minami IC-Takaya JCT in June last year. Congestion is occurring in the obi area near the Kawaguchi Higashi IC due to traffic congestion, and we anticipate that congestion will occur at the location during the construction period, just as in normal times.

Due to this construction, congestion will be expected on the Tohoku Expressway Expressway, which connects to the outer ring road, and the Metropolitan Expressway No. 5 Ikebukuro Line, as well as the surrounding general roads.
