Illinois Official Highway Map

Detail from Illinois Official Highway Map

Free, official road maps seem to be an endangered species. Via MAPS-L, a press release from Illinois’s Department of Transportation announcing that, for the second year running, their Official Highway Map would be available free of charge thanks to a sponsorship deal with Best Western. The previous version (2005-2006) of said map is available online, but as a 12.3-megabyte PDF file. Other maps of Illinois from the DOT web site.
