Tier Two - Complete

Study Area

The Illinois Department of Transportation (IDOT), the Indiana Department of Transportation (INDOT), and the Federal Highway Administration (FHWA) completed the first tier of the Illiana Corridor study project in January 2013 with approval of the Record of Decision (ROD), advancing one corridor and a no-build alternative into the second tier of the study project.  The recommended corridor, known as “B3,” extends from I-55 near Wilmington, Illinois, 46.8 miles east to I-65 near Cedar Lake, Indiana, and was identified as the selected preferred corridor alternative during the first tier of the planning process.
