The Heritage Lake maintenance staff will be out treating the roads until 11 pm tonight. They will resume around 3 am Saturday morning, and will monitor conditions throughout the day. Please drive cautiously, the subdivision roads are a little slick, but some county roads like Dee-Mack Rd and Broadway have many areas of black ice.
Remember that IDOT Road Conditions can be found at http://apps.dot.illinois.gov/winterroadconditions/pages/wrc.htm
