Official Highway Map

  The Illinois Official Highway map is your guide to travel throughout Illinois. It is published every two years.

The Department of Transportation offers two maps to the public. One is the standard regular print map and the other is a large print map. The large print map is approximately 38 percent larger than the regular map and has half of the state on one side of the map and the other half on the reverse side. The reverse side of the regular print map shows enlarged metropolitan areas for more than a dozen communities across the state.

Both maps are available free of charge at all Interstate Welcome Centers and IDOT's nine district offices.
