The Illinois Tollway is rebuilding and widening the Jane Addams Memorial Tollway (I-90) as a 21st century, state-of-the-art corridor linking Rockford to O’Hare International Airport. Visit the Illinois Tollway Website for more information on the construction projects.
In 2012, prior to construction we conducted surveys of amphibians, reptiles, fishes, and mussels at 14 stream crossings.
We continue to monitor these areas post construction.
We are also monitoring biological communities along the I-90 bridge over the Fox River.
