Official Highway Map
The Illinois Department of Transportation provides maps upon request to be used strictly for transportation-related purposes. At this time, we are limiting 1 map per email/mailing address. If you are a school, library, law enforcement agency or any other institution need of a larger volume, the request will need to be submitted from an official school/library/law enforcement email account.
The Illinois Official Highway Map is published every other year and is available to the public free of charge. The electronic version of the map is available here: Illinois Official Highway Map PDF.
Official Highway paper maps are also available by order. See the Map Ordering section below for more information on ordering maps.
