Map Ordering
To order hard copies of Illinois Official Highway or Bicycle Maps please complete a Illinois Map Request.
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 in need of a larger volume, the request will need to be submitted from an official school/library/law enforcement email account to DOT.Maps@illinois.gov.
