Any municipality may by ordinance provide for the establishment of a Bridge Commission, to consist of 3 persons resident therein to be appointed by the Mayor, for terms of 4 years and until their successors are appointed; provided that of the Commissioners first appointed, one shall be appointed for a term of 2 years, one for 3 years and one for 4 years, as designated by the Mayor. The Commissioners shall receive no compensation for their services but shall be reimbursed for actual expenses incurred in the discharge of their duties. Vacancies in the office of any Commissioner shall be filled by the Mayor by appointment for the unexpired term.
The ordinance may vest in the Bridge Commission the duties and responsibilities incident to the acquisition or construction of the bridge project, the operation and maintenance of the bridge project, the execution of contracts for the acquisition, construction and maintenance thereof, the collection of the tolls and other charges of the municipality for transit over or use of the bridge, and such other powers as the corporate authorities may deem necessary or desirable. Nothing in this section shall be construed to authorize a delegation of power to the Bridge Commission to adopt any ordinance pertaining to the issuance of revenue bonds or refunding revenue bonds or the fixing of rates of toll.
