For the purpose of acquiring by purchase or otherwise or the constructing of any such bridge, the county board of each such county is authorized to borrow money and in evidence thereof to issue the bonds of such county, and to refund the same from time to time, payable solely from the revenues derived from the operation of such bridge. Such bonds may be issued as serial or term bonds, shall mature in not to exceed 40 years from the date thereof, and may be made redeemable, prior to maturity, with or without premium. Such bonds may be issued in such amounts as may be necessary to provide sufficient funds to pay the cost of acquiring or constructing such bridge and the approaches thereto, including all property real or personal, necessary or incidental in the acquisition or construction of such bridge and its approaches, including reasonable legal and engineering, traffic survey, and architectural fees, costs of financing, and interest during construction and for not less than 12 months thereafter. Such bonds shall bear interest at a rate not to exceed that permitted in "An Act to authorize public corporations to issue bonds, other evidences of indebtedness and tax anticipation warrants subject to interest rate limitations set forth therein", approved May 26, 1970, as amended, payable semi-annually. Bonds issued under the provisions of this Division of this Article have the qualities and incidents of negotiable instruments under the laws of the State of Illinois, shall be executed in the name of the county by the chairman of the county board and the county clerk of such county, and shall be sealed with the corporate seal of the county, and the interest coupons attached to such bonds shall be executed by the facsimile signatures of such chairman and county clerk, and such officials by the execution of such bonds shall adopt as and for their own proper signatures their respective facsimile signatures appearing on such coupons. In case any officer whose signature appears on any such bonds or coupons ceases to be such officer before delivery of such bonds, such signatures shall nevertheless be valid and sufficient for all purposes, the same as if such officer had remained in office until such delivery.
Such bonds may be registered as to principal at any time prior to maturity in the name of the holder on the books of the county in the office of the county treasurer, such registration to be noted on the reverse side of the bonds by the county treasurer, and thereafter the principal of such registered bonds shall be payable only to the registered holder, his legal representatives or assigns. Such registered bonds shall be transferable to another registered holder, or back to bearer, only upon presentation to the county treasurer with the legal assignment duly acknowledged or approved. Registration of any such bonds shall not affect negotiability of the coupons thereto attached, but such coupons shall be transferable by delivery merely.
All such bonds issued by any such county shall be sold in such manner and at such time as the governing body shall determine. Whenever the governing body of any such county determines to issue bonds as provided for in this Division of this Article, it shall adopt an ordinance describing in a general way the bridge to be acquired or constructed and its general location. Such ordinance shall set out the aggregate amount of the estimated cost of the acquisition or construction of such bridge, as prepared by the engineers employed for that purpose, determine the period of usefulness thereof and fix the amount of revenue bonds to be issued, the maturity or maturities, redemption privileges, the interest rate, sinking fund, and all other details in connection with such bonds, including such reserve accounts as the county board of such county may deem necessary. Such ordinance may contain such covenants and restrictions upon the issuance of additional revenue bonds thereafter as may be deemed necessary or advisable for the assurance of the payment of the bonds thereby authorized. Revenue bonds issued under the provisions of this Division of this Article shall be payable solely from the revenue derived from such bridge, and such bonds shall not, in any event constitute or be deemed an indebtedness of such county within the meaning of any constitutional provisions or statutory limitation as to debt, and it shall be plainly stated on the face of each bond that it does not constitute an indebtedness within any constitutional or statutory limitation. Such ordinance shall be published within 30 days after its passage in a newspaper, published and having a general circulation in such county, and shall not become effective until 10 days after its publication.
