2. Detour

For detours, please refer to the attached document [PDF: 277KB].
The detour will increase travel time, so please allow yourself plenty of time when traveling.

3. Construction overview

We will carry out pavement repair work and floor slab repair work at the In-bound line entrance ramp and Out-bound line exit ramp of the Yamagata Expressway Sekizawa IC. Since it is not possible to carry out construction under normal lane restrictions, it is necessary to close the ramp and carry out the work.
Therefore, we will carry out construction intensively and efficiently so as not to cause as much inconvenience to our customers as possible. This is necessary for the safe and comfortable use of Expressway, so we ask for your understanding and cooperation.
