This bill designates the Bayou Bienvenue Bridge on Louisiana Highway 47 in Chalmette, Louisiana, as the "Senator Samuel B. Nunez, Jr. Crossing." The legislation aims to honor Senator Nunez by officially naming the bridge after him.

Additionally, the bill mandates that the Department of Transportation and Development, or its contractors, are responsible for erecting and maintaining signage that reflects this new 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 $550 per sign.
