Road Jurisdiction and Maintenance

The jurisdiction and maintenance of public roads can be confusing. A unit of government who has jurisdiction over a public road or a segment of a public road has the authority and obligation to administer, control, construct, maintain and operate that road or segment of road. The units of government with jurisdiction comprising all of the public roads in the unincorporated areas of DeWitt County are the State of Illinois, the County of DeWitt and the 13 Township Road Districts in DeWitt County. Please click here for a map to determine the jurisdiction of a road or segment of road. You'll find in the legend of the map how highways under the jurisdiction of the State of Illinois are identified as either U.S. Routes, IL Routes or Interstate Routes. You'll also find how highways under the jurisdiction of the County of DeWitt are identified as County Highways. You will not find identification for the township roads shown on the map as those roads consist of all highways lying outside the corporate limits of municipalities that are not state or county. Once you have determined the jurisdiction please contact the proper highway authority. You can reach IDOT at 217-465-4181, the DeWitt County Highway Department at 217-935-2438 and the township highway commissioners from the contact information provided by clicking here.
