NEXCO EAST Niigata Regional Head Office (Nishi-ku, Niigata city, Regional Head Office president: Yoshio Shiraishi) is the thickness of the lining concrete that occurred during the Kumasaka tunnel construction of the Joshinetsu Expressway 4-lane project (between Toyota Iiyama IC and Shinanomachi IC) currently under construction. We are continuing to conduct surveys on inappropriate construction such as lack of space and voids, but since we newly confirmed that the thickness of shotcrete was insufficient, we will hold a local briefing session (interim report) next time. It will be held as follows.
