This bill designates a portion of Louisiana Highway 433 in St. Tammany Parish as the "Captain Walter B. Abney Memorial Highway." The specific section of the highway to be named is from United States Highway to United States Highway 190.

Additionally, the bill mandates that the Department of Transportation and Development, or its contractor, is responsible for erecting and maintaining appropriate signage for this designation. However, this is contingent upon the receipt of local or private funds that cover the department's actual costs for the signage, which cannot exceed five hundred fifty dollars per sign.
