For the maintenance of the highways the authorities collect a nominal toll per vehicle on the Chicago highways.

The following are the different maximum toll charges for different vehicles:

- Passenger Car (2 axle) - $2

- Small Truck (2-axle) - $3

- Medium Truck - $4.5

- Large Truck - $8

The commuters can also avail I-PASS and E-ZPASS facilities that save their time and also money. Every toll lane is made to accept the I-PASS so that the motorists can travel without much waiting. Also if you are paying through the I-PASS you are only paying the half of the amount.
