House Bill No. 149 designates a portion of United States Highway 190 Business East in Slidell, Louisiana, as the "Senior Police Officer Trevor Abney Memorial Highway." The designated section begins at the intersection of Beech Avenue and East Interstate 10 Service Road and ends at the intersection of United States Highway 190 East and Military Road. This memorial designation honors Senior Police Officer Trevor Abney.

The bill also directs the Department of Transportation and Development (DOTD) to erect and maintain appropriate signage to reflect this designation. However, the implementation of the signage is contingent upon the receipt of local or private funds that cover the DOTD's actual costs for materials, fabrication, mounting posts, and installation, with a maximum limit of $2,250 per sign.
