Current Regulations/ Traffic Congestion Forecast

The critical situation of aging expressways.

The Expressway now aging. With the aging of bridges and tunnels, the Expressway that has continued to support the Japanese economy and life is secretly screaming.

In addition to the aging that comes with years past, the increase in the number of large-sized vehicles and in the total weight of vehicles, the spraying of antifreeze and more have made the aging worse.​ ​

To pursue 100% safety and 100% security

Not only do the expressways support the life and economic activities, they also play an important role as emergency transportation routes in the event of a disaster such as the Great East Japan Earthquake, heavy rain, heavy snowfall and so on. You cannot do without them to ensure a safe and secure way of living.​ ​

In order to continue fulfilling the role of the network supporting the infrastructure such as economy, politics, medical care and disaster prevention, we need to guarantee safe and secure expressways in the future and maintain the functioning of the expressway network in the long run. To achieve this, It is necessary to take drastic measures now.

We appreciate your understanding and cooperation for the future constructions.​ ​

We may cause inconvenience with traffic regulations for large-scale constructions such as a bridge replacement or tunnel renovation.
In order to reduce the social impacts accompanying traffic regulations as much as possible, we are dedicated to sharing the right and thorough information with expressway drivers and people living alongside constructions, while providing appropriate detour paths with notifications about them, coming up with wise plans for traffic regulations and attempting to reduce construction.

We are ensuring expressways that are safe and secure for future generations. Thank you for your understanding and cooperation.​ ​
