Louisiana Revised Statutes Tit. 48, § 220. Width of right-of-way

A. The width of rights-of-way for highway construction shall be fixed by the chief engineer of the Department of Transportation and Development. Generally, the width may be fixed in a manner sufficient, in the judgment of the chief engineer, to provide presently and in the future for the public interest, safety, and convenience. Specifically, the width may be fixed in a manner sufficient to adequately accommodate the future improvement of the highway by the construction of additional lanes of pavement, service roads, intersections, traffic distribution devices, and grade separations. It may be fixed to provide sight distances and insure stability and lateral support for the embankments, structures, and appurtenances to the highway and to provide for proper drainage.

B. Notwithstanding any provision of law to the contrary, fences may be erected up to, but not within, the boundary of the designated right-of-way of any road or highway in Ward 1 or Ward 5 in Beauregard Parish.
