2. Construction overview

Ken-O Road Kanzaki IC ~ Daiei JCT, Keiyo Road 　At Miyanogi JCT and Sakura IC on the East Kanto Road, pavement repair work will be carried out because road surface damage has occurred. All sections where this work will be carried out will be one lane on each side, and since construction cannot be carried out under normal lane regulations, it is necessary to close the road or close the ramp to carry out the work.
Therefore, in order to avoid inconveniencing customers as much as possible, we will close roads or close ramps at night on weekdays when there is little traffic, and carry out construction intensively and efficiently. This is necessary for safe and comfortable use of Expressway, so we ask for your understanding and cooperation.
