Miss. Code § 65-21-23
When a bridge shall be necessary over a stream or any other body of water which divides one county from another, or a bridge over a river or any other body of water flowing from one county into another shall be necessary at the intersection of the river and the line between the counties, (or necessary to two or more counties and within five miles of each of said counties), the boards of supervisors of all interested counties to which it may be necessary may join in the agreement for building, repairing, and keeping the same. The charge therefor shall be defrayed by all such interested counties as may be agreed upon by the boards of all of said counties; and if the board of supervisors of one county refuses to join in the agreement, the other county or counties may construct the bridge, with the consent of the board of supervisors of the county refusing or failing to join, and have exclusive control of it and charge toll thereon against citizens of the county not joining in the building. The will of the several boards of supervisors hereunder shall be expressed by a resolution duly adopted, entered on the minutes, and published in a newspaper in the county, if there be one; if there be no newspaper in the county, then in a newspaper in an adjoining county, for three weeks before such resolution shall take effect.
