Kanto Regional Head Office

NEXCO EAST Kanto Regional Head Office (Taito-ku, Tokyo) is a soul that crosses the Arakawa River between Gaikan Expressway (gaikado) Wako north interchange (IC) and Toda west IC (gai). We will carry out repair and reinforcement work on the steel deck of the bridge.

This work requires repairs and reinforcement work because cracks that may be caused by metal fatigue have occurred in the steel deck due to repeated passage of large vehicles.

Since traffic control will be implemented to reduce the number of lanes during construction, it is expected that there will be a traffic jam of about 10 km during the morning and evening hours when traffic is heavy and it will take an hour or more to pass through, and congestion on the surrounding general roads as well. I will.

We apologize for the inconvenience, but we ask for your understanding and cooperation in using public transportation and detouring to general roads when you go out.

For road traffic information and information such as construction decision on the day, please contact NEXCO EAST Customer Center (TEL: 0570-024-024), Japan Road Traffic Information Center (TEL: 050-3369-6600) And so on.
