The resolution or resolutions authorizing the superhighway bonds shall prescribe all the details thereof and shall provide for the levy of a direct annual tax upon all the taxable property within the county to pay the principal thereof and interest thereon as it matures. This tax shall be in addition to and exclusive of the maximum of all other taxes authorized to be levied by the county. Tax limitations applicable to the county provided by this Code and by other statutes of this State shall not apply to taxes levied for payment of superhighway bonds. However, taxes provided to be levied for payment of superhighway bonds shall not be in excess of the constitutional limitation of seventy-five cents per $100 valuation unless that excess is authorized by a vote by the people of the county. Such resolution or resolutions shall also provide that when received, each of said county's allotments of moneys from the Motor Fuel Tax Fund of this State shall, except as hereinafter provided, be paid into the superhighway bond and interest sinking fund account or accounts required to be created by Section 5-33005, which provision shall be deemed additional security for payment of the superhighway bonds and interest thereon and shall be irrepealable by the county board so long as any superhighway bonds and interest thereon are unpaid. If more than one bond resolution is adopted under the authority of this Division, each such allotment of moneys from the Motor Fuel Tax Fund shall be apportioned among the sinking fund accounts for such bond issues in proportion to the principal amount of each issue. If and when the moneys received from the Motor Fuel Tax Fund by such county during any calendar year and deposited in the superhighway bond and interest sinking fund account or accounts equal the amount of taxes levied and next to be extended for principal of and interest on all superhighway bonds issued under authority of this Division, the balance of the moneys received from the Motor Fuel Tax Fund during that calendar year may be used by such county for such other purposes as permitted by law. A certified copy of the bond resolution or resolutions adopted under authority of this Division shall be filed with the county clerk of the county and shall constitute authority for the extension and collection of superhighway bond and interest taxes as required by the constitution. A certified copy of the bond resolution or resolutions shall also be filed with the Director of the Department of Central Management Services of this State.
