3 Outline of construction

At the Kawaguchi JCT ramp going from the inside of the outer ring road to the Tohoku Expressway road, the road surface is damaged due to aging, so we will carry out pavement repair work. The section where this work is done is one lane, and it is necessary to work by closing the ramp because the construction can not be done by the usual traffic lane regulation.

Therefore, we will close the lamp during the night from Sunday to Thursday, where traffic is light, and carry out the construction intensively and efficiently, so as not to bother our customers as much as possible. As it is construction necessary to use Expressway safely and comfortably, I would like understanding and cooperation.
