The county court shall have the superintendence and administration of the construction, reconstruction, repair and maintenance of bridges and approaches to bridges situated within municipalities and at the time of the adoption of this chapter remaining under the control and jurisdiction of the county court. The county court shall also have like authority over public landings. The term "roads and bridges" in this article shall be construed to mean the bridges and approaches to bridges which under this section remain within the jurisdiction of the county court, unless the context clearly requires a different meaning.
Pursuant to section two, article four, this chapter, the county court shall upon the first day of July, nineteen hundred thirty-three, relinquish to the state road commission its authority over county-district roads, and shall thereafter neither construct, reconstruct nor maintain any road or bridge except as is specifically authorized by this article.
The state road commissioner may purchase or rent from any county court any or all road equipment and materials in their possession and shall give preference in the purchase of such machinery from the county courts that may be needed by the commission and not needed for the maintenance and repair of the roads, bridges and landings remaining under their control.
