2. Construction overview

Due to damage to the pavement at the ramp of Daiei PA on the East Kanto In-bound, pavement repair work will be carried out. The section in which this work will be carried out is a single lane, and since the work cannot be carried out under normal lane restrictions, it is necessary to close the ramp to carry out the work.

This work is necessary to ensure that customers can use Expressway safely and comfortably, so we ask for your understanding and cooperation.
