Town of Mooresville issued the following announcement on Aug. 11.
As part of the West Wilson Avenue Improvement Project, storm drainage is currently being installed on the north side of West Wilson Avenue (near Hillside Drive). Traffic in the area should anticipate delays due to the lane closure in that area. There are flaggers in place to help mitigate back-ups. Thank you for your patience as this work is being performed.
