NEXCO EAST Yamagata Management Office (Yamagata City, Yamagata Prefecture) has a provisional two-lane section (one lane on each side) from the E48 Yamagata Expressway Yamagata Junction (JCT) to the Tsukiyama Interchange (IC). In the meantime, we will close the road at night as follows due to the renewal work of the tunnel lighting equipment.
In addition, NEXCO EAST Tsuruoka Management Office (Tsuruoka City, Yamagata Prefecture) is conducting pavement repair work between the E48 Yamagata Expressway Yudonoyama IC and Tsuruoka IC on the provisional two-lane section (one lane on each side). Therefore, we will close the road at night as follows.
Therefore, when you go out, please leave with plenty of time, and when you drive, please detour to National Highway No. 112 etc.
We apologize for the inconvenience caused to customers who use the Expressway, but we ask for your understanding and cooperation in the construction work necessary to use the Expressway safely and comfortably.
