Outline of road closure work

Joshin-Etsu Expressway Shinanomachi IC-Nakago IC was opened in October 1997, and the Nakago IC-Joetsu JCT was opened in October 1999 with provisional 2-lane operation. After that, in response to the business license change in April 2012, we have started a 4-lane business, but this work is progressing, and as a preparatory work for the completion of 4 lanes, paving work of the service lane and facility relocation We will carry out renewal work by closing the road.
