Route 16 under road construction between Grange Hall Rd and Macoupin Co. line

If traveling to and from Jerseyville, it is most likely drivers will experience some road construction on their daily commutes. On Aug. 17, the Illinois Department of Transportation (IDOT) announced that intermittent lane restrictions will begin on IL 16 between Grange Hall Rd. and the Macoupin Co. Line on Thursday, Aug. 19, weather permitting. Two-way traffic will be maintained by the use of flaggers. These restrictions are needed to place a new asphalt surface and the work is expected to be completed by mid-November. Drivers are urged to reduce speed, be alert for changing conditions, obey all construction signage, and refrain from using mobile devices while approaching and traveling through the work zone. The contractor on this project is the C. E. Mahoney Co. of Swansea, Illinois.
