Illiana Expressway Project

Both the Departments of Transportation in Indiana and Illinois are actively working on a new limited highway facility from I-65 south of Crown Point, IN, to I-55 south of Joliet, IL.  This facility dubbed the Illiana Expressway would connect the south Chicago Suburbs with NW Indiana along its proposed 47-mile route.  The process behind the development of the expressway is complex, and this web page will serve as an information clearinghouse regarding important dates and documents relating to approvals and possible construction of the facility.  Documents are both public and private in nature, and include all updated public comments.  Please scroll down to the content you wish to view regarding the project.  This will also include any public comment dates and forms you can submit online.   Additional questions on the expressway project can be forwarded to Mitch Barloga at
