The ordinance or resolution of the board of county commissioners authorizing the execution of any contract relating to any such bridge, or fixing the compensation to be paid for the use of any such bridge or of the tracks thereon, as provided in Kan. Stat. Ann. §§ 68-1404 and 68-1409, shall be read in full at three regular meetings of the board, and promptly upon its final adoption, shall be published in the official county newspaper, and shall become effective upon the expiration of ten days after the publication thereof unless, within said ten days after said publication, a taxpayer of the county, or the governing body of a city within the corporate limits of which such bridge and the approaches thereto are located, or a civic organization of such city or county shall file written objections with the county clerk of such county to any of the terms of the contract authorized by such ordinance or resolution. If any such written objections are so filed, the board of county commissioners shall hold a public hearing on such written objections, notice of the time and place of such public hearing to be given by one publication thereof in the official county newspaper at least ten days prior to the date of said hearing.

Upon such hearing, full opportunity shall be given to the objectors filing such written objections to present any evidence or arguments pertaining to their objections to the terms of the contract authorized by said ordinance or resolution, and the board of county commissioners shall then, after consideration of said evidence and arguments, further consider said ordinance or resolution and contract as upon the previous final reading and adoption thereof, having full power and authority to amend, modify or change the terms of said ordinance or resolution and contract, subject to the acceptance of such amendments, modifications or changes by the other party to said contract, or to readopt said ordinance or resolution and authorize said contract as originally proposed and adopted, or to reject the same, the action of the board of county commissioners upon said ordinance and resolution and the contract authorized thereby and accepted by the other party thereto, to become final and effective at the expiration of ten days from the date of said action.

No contract entered into pursuant to the provisions hereof, whether for a definite period or on a terminable basis, shall extend for more than twenty years, and any extension beyond twenty years shall be deemed a new contract, and shall not become effective until the foregoing requirements are met.
