Senate Bill No. 104 designates a section of Louisiana Highway 1 in Pointe Coupee Parish as the "Ernest J. Gaines Memorial Highway." The designated portion begins at the intersection of Louisiana Highway 1 and Louisiana Highway 78, extending to the Pointe Coupee Parish line before it crosses into Avoyelles Parish.

The bill also mandates that the Department of Transportation and Development (DOTD) is responsible for erecting and maintaining the signage for this designation. However, the costs for materials, fabrication, mounting posts, and installation of each sign are capped at $750, and the department can only proceed with the signage if local or private funds are provided to cover these costs. The effective date for this designation is set for August 1, 2026.
