County

The county classification maps depict the rural classification of the road network outside the city urban area within the selected county and emphasize the display of the road network outside the cities and villages.

City

The city classification maps depict the urban classification of the road network primarily for the selected city's urban area and emphasize the display of the road network inside the cities and villages at a larger scale than the county maps.

Township

The township classification maps depict the urban classification of the road network for larger city urban areas that do not fit on one single map sheet (eg: Chicago, South Beloit, Rockford, Peoria and E. St. Louis Urban Areas) and emphasize the display of the road network on a regional basis without regard to specific city and village boundaries.

IDOT Districts

The district classification maps depict the rural classification of the road network and emphasize the display of the road network between the counties of the selected district.
