605 ILCS 5/10-902
The Department may maintain and operate any ferry acquired under Section 10-901 of this Code as a free ferry service for the conveyance of persons, motor vehicles and other property across the Illinois River so long as such operation is justified by the amount of traffic using such ferry. The location of ferry landings and the route of any ferry acquired and operated under the authority of these sections shall be such as the Department determines will be most convenient to the majority of the users of such service considering economy of operation of such service. If deemed desirable and feasible by the Department the operation of such service may be relocated by the Department and new approaches and facilities constructed to serve the relocated site of operation.
