About the Study

Study Area

Now more than 100 years after Burnham’s plan, this region is a different place and has additional demands for transportation options. That is why this Environmental Impact Study (EIS) began with a blank slate.

The Illiana study area for Tier One was located in southern Will County and northern Kankakee County in Illinois and southern Lake County in Indiana. The study area generally was located between I-65 on the east, I-55 on the west, U.S. 30 on the north, and north Kankakee County on the south.
