This bill designates specific portions of highways in Louisiana to honor individuals. It establishes the elevated portion of Interstate 12 in St. Tammany Parish as the "Patricia 'Pat' Brister Memorial Bridge" and a segment of United States Highway 51 in St. John the Baptist Parish as the "Arnold J. Labat Memorial Highway." The bill mandates the Department of Transportation and Development to erect and maintain appropriate signage for these designations, contingent upon the receipt of local or private funds that cover the actual costs of materials and installation.

Additionally, the bill specifies that the costs for the signage should not exceed $1,680 for the Patricia 'Pat' Brister Memorial Bridge and $550 for the Arnold J. Labat Memorial Highway. This ensures that the financial responsibility for the signage falls on local or private sources rather than the state budget. The bill aims to honor the contributions of these individuals while also establishing clear financial guidelines for the associated costs of the memorial signage.
