Statewide

  • Functional Classification Maps
The Illinois DOT (IDOT) has confirmed that the GIS-based interactive maps are more current than the 5-Year PDF maps. The PDF maps require additional manual steps to update and may lag.
It is important to note that the interactive (GIS-based) functional classification map uses a third-party base map whose accuracy in road naming cannot be guaranteed. While the functional classification (FC) indications are provided by the State, the third-party base map data is not an appropriate external source of information (see Using external sources).'
For additional information on matching road types to FC, please see Road Type (Functional Classification).
