South Main/Greenhill Intersection Improvements

Beginning the week of Monday, March 28th, 2022, the contractor will begin Stage 1 reconstruction of the Greenhill Road and S. Main Street intersection. In order for the contractor to begin pavement removal, southbound S. Main Street lane closure will be required. The lane closure will be in effect while the contractor works on pavement removal, storm sewer, and new pavement on the northwest and northeast corner of S. Main & Greenhill. The intersection will be converted to a temporary all-way stop controlled intersection, and southbound S. Main Street traffic will be advised to detour using Highway 27/58 from University Avenue to Greenhill Road. Below you will find a map with the closure area highlighted.

For safety's sake, please stay away from the construction area. Heavy equipment will be moving back and forth on the closed street. It would be advisable to stay behind the sidewalk on the property side during the reconstruction work.
