Restoration of Expressways after Disasters
In the event of disasters such as earthquakes, we swiftly check roads & facilities and works toward restoration in an effort to provide traffic services.
Examples of Restoration Activities in the Aftermath of the Great East Japan Earthquake
The Great East Japan Earthquake on March 11, 2011, caused numerous damage to Tohoku and Joban Expressway, such as cracks and differences in road surface levels, collapses of embankments, and damages to expansion joints. Right after the earthquake, we enforced road closures of sections for about 2,300 km and conducted emergency inspections and temporary restoration. We were able to ensure emergency traffic routes on the following day of the earthquake, and 13 days after the disaster, we lifted road closures for almost all sections of the expressways.

Assistance with Rescue Activities
We are equipped with emergency heliports and other facilities to assist in emergency lifesaving activities and rescue missions when disasters occur, and we conduct training with relevant organizations.
Use of Rest Areas as Emergency Operation Bases
After the Great East Japan Earthquake struck, rest areas on the expressways were used as assembly bases and relay points for the Self-Defense Forces, firefighters, and other organizations. Due to this experience, we have been creating rest areas with lifeline backup facilities such as private power generators and wells, and these can be used as part of a common disaster risk management office, so that relevant organizations can facilitate disaster rescue activities effectively in the event of natural disasters. We also jointly implement emergency drills, etc., with the relevant organizations.
