3. Construction overview

At Kan-Etsu Expressway Oizumi IC, the expansion joints installed at the joints of the bridges have been damaged due to deterioration over time, so we will replace them with more durable steel expansion joints.
The section where this work will be carried out is a single lane, and since the construction cannot be carried out under normal lane restrictions, the work will be carried out with the ramp closed.
Therefore, in order to minimize inconvenience to customers, we will close the ramps at night when there is little traffic, and carry out construction work intensively and efficiently.
We ask for your understanding and cooperation as this work is necessary for safe and comfortable use of Expressway.
