NEXCO EAST Kanto Regional Head Office (Taito-ku, Tokyo) will carry out tunnel repair work for the Nagano area between the Nagano Expressway (Nagano Road) Asa Interchange (IC) and Sarah IC (Out-bound line).

This work requires repair work because a part of the paved road surface of the tunnel has been damaged ( Attachment 1 [PDF: 172KB] ).

In the construction work, traffic restrictions that reduce the number of lanes must be enforced day and night, including weekends and holidays, and traffic jams are expected on weekends and holidays. In particular, we predict that construction congestion will occur for a maximum of 5 to 6 km during the three consecutive holidays in the morning and evening when traffic is heavy.

We apologize for the inconvenience, and we appreciate your cooperation. Also, when you go out, please take time to go out.

For road traffic information, please visit NEXCO EAST Customer Center, Japan Road Traffic Information Center, etc. For details, see 2. Please see (2).
