ITR Concessions Co. LLC, which manages the highway, can raise tolls because of its lease agreement with the state.
Starting in July, a trip on I-90 from the Ohio state line to the Chicago Skyway will cost $13.50 for a typical two-axle passenger vehicle, a 9.9% increase.
Class 7 vehicles, such as tractor-trailers, will pay $158.83 for the cross-state route.
Tolls vary according to vehicle class and distance travelled.
