Starting this Jan 1, 05 the Illinois toll road system has raised tolls by as much as 300% in certain times and loads. We in Illinois have the option to purchase what they call an I pass transponder that allows the driver of a vehicle to use the express lanes when entering a toll plaza. But under the new system, if you do not have the I pass, you pay 100% more in the toll for your car. TRUCKS have there own rates. Example, You are pulling a double axle trailer with your dully pick up. The toll system now says that you will be charged for 5 axles, The Dully counts as 2, thus under the old system you would have payed 80 cents to 1.00 dollars at every major toll plaza. Now you will pay 2.00 to 2.50 at each toll plaza. But it could be higher if you are on the road during rush hours. Am / Pm. Even we who live in this area, do not know.
So watch I-88 I-90 I-94 in the Chicago area.
