The powers conferred by this article shall be in addition to the powers conferred by any other law, general, special or local. This article, without reference to any other statute or to any charter, shall be deemed full authority to purchase, build, improve, own, and operate the revenue producing system by this article authorized; to fix, maintain, and collect toll rates for the facilities afforded by such toll bridge; and to issue and sell bonds by this article authorized; and shall be construed as an additional and alternative method therefor, any provision of the laws of the state or any charter of any municipality to the contrary notwithstanding. Where no funds are pledged as security for bonds to be issued by the municipality or other political subdivision other than the revenues arising from the tolls of the bridge to be purchased, erected, or extended, bonds may be authorized and issued under this article by ordinance incorporating the terms and conditions of said bonds passed by the governing authority of such municipality, county, taxing district, or other political subdivision, which article, resolution, or ordinance shall be spread in full upon the minutes of such political subdivision. It shall not be necessary to submit same to an election of the qualified voters of such political subdivision unless moneys for the payment of such bonds or interest thereon or maintenance of such bridge, or construction thereof, shall be pledged from taxes or other funds other than the revenue alone arising from the tolls collected on such bridge. In such event the proposition for the pledging of such additional funds and the issuance of such bonds shall be submitted for the approval of same to the voters of the municipality or other political subdivision at a special election called therefor according to law, and after a majority of the qualified electors voting at said election have voted in favor of the proposed bond issue. Where bonds have been authorized under this article, it shall not be necessary to make publication of any ordinance, resolution, notice, or proceedings relating thereto.
