 Because both northeastern Illinois and northwestern Indiana have state- and federally-recognized regional planning agencies which have published formal regional plans, under federal law the Illiana Expressway must be reflected in those plans.The Illiana was listed as a fiscally unconstrained project in the "GOTO2040" plan published by the Chicago Metropolitan Agency for Planning (CMAP), and as an "illustrative" project in the 2040 Plan published by the Northwestern Indiana Regional Planning Commission (NIRPC).The Illiana Corridor planners requested both planning agencies to amend those plans to include the expressway as a regional priority project.
