Four. Construction overview

At the Ipponmatsu Tunnel located between Asagi IC and Koshoku IC on the Nagano Out-bound Line, tunnel reinforcement work is being carried out to prevent road surface swelling and damage due to expansion of the tunnel ground.
In implementing the tunnel reinforcement work, on August 22, 2023, protective fences were constructed to separate the lanes where customers are traveling and the lanes where construction is being performed, and on September 5, 2023, We will carry out construction work to remove the protective fence. Since this construction cannot be carried out under normal lane restrictions, the construction will be carried out after closing the road at night on weekdays when there is little traffic.

[Details of tunnel reinforcement work]
In order to create a stronger ring-shaped structure for the tunnel where excessive force is applied from around the tunnel, an invert is installed to improve stability. Specifically, concrete (invert) will be installed to reinforce the bottom of the tunnel after the excavation of the road surface, and then paving work will be carried out to restore the road to a drivable one.

In order to minimize the inconvenience to customers, we will close the road at night on weekdays when the traffic volume is low, and carry out the construction work intensively and efficiently. We ask for your understanding and cooperation as this work is necessary for safe and comfortable use of Expressway.
