Louisiana Revised Statutes 48:192 – Engineering standards; naming state highways
A. The department shall immediately establish and maintain design standards for the functional classifications of state highways, following the best engineering practices and experiences for the construction of all roads, bridges, drainage structures, or other work which may be necessary from time to time which said standards shall comply with all federal regulations necessary to obtain federal aid for road and bridge construction in Louisiana.
B. The department may take into the state highway system any parish or municipal road needed to complete a necessary segment of a road; however, the total length of the state highway system established hereby is not exceeded and said road taken into the state highway system will not necessarily delay the needed construction and maintenance of roads on the existing system. The department may negotiate an exchange of roads in any parish or municipality for roads on the state-maintained highway system provided that the roads taken into the system in said exchange will not necessarily delay needed construction and maintenance of roads on the existing system.
C. The department may at any time the need justifies transfer a state highway from one functional classification to another.
D. Notwithstanding any other provision of law to the contrary, it shall be unlawful to name any state highway except by an Act of the legislature.
