Louisiana Highway 49 (LA 49) is a state highway located in Jefferson Parish, Louisiana. It runs in a north–south direction along Williams Boulevard from U.S. Highway 61 (US 61) to an intersection with Joe Yenni Boulevard and 44th Street in Kenner. The route serves as the principal north–south thoroughfare of the city of Kenner, a suburb of New Orleans, and is lined almost continuously with shopping centers, eating establishments, and other commercial services. It is also heavily traveled due to its proximity to Louis Armstrong New Orleans International Airport, and it intersects many of the major east–west routes through neighboring Metairie, including Interstate 10 (I-10), Airline Drive (US 61), West Metairie Avenue, Veterans Memorial Boulevard, and West Esplanade Avenue. LA 49 is primarily known by its local name of Williams Boulevard, and signage identifying the route is only present at its two major junctions, I-10 and US 61.
