3 Outline of construction

Tohoku Expressway In-bound In the Kawaguchi JCT ramp going from the line to the inside of the outer ring road, road surface damage has occurred due to deterioration over time, so pavement repair work will be carried out. The section where this work is done is a single lane, and it is necessary to close the ramp before starting the work because the work cannot be done under normal lane regulations.

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.
