Illinois is rebuilding the tollway (I-90) between Rockford and Elgin, but that does not stop them from charging tolls. If you have driven on the Tollway recently, you know that it is slow going, congested, and dangerous. The speed limit is 45 MPH all of the way from Rockford to Elgin. If there is an accident, you could be delayed for hours and miss your plane if you are going to O’Hare. Consider, an alternate route bypassing the Tollway and rejoining it at Elgin around Randall Road where the construction ends!
