Four. Construction overview

Kan-Etsu Expressway expansion and contraction device installed at the joint between bridges has been damaged due to aging, so we will replace it with a more durable steel expansion and contraction device. The section where this work is to be carried out is a one-lane ramp, and since it is not possible to carry out the work under normal lane regulations, it is necessary to close the ramp and carry out the work.
Therefore, in order to avoid inconvenience to customers as much as possible, we will close the lamps at night when the traffic is light and carry out the construction intensively and efficiently. Expressway safely and comfortably, so we ask for your understanding and cooperation.
