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. ==Route description== From the south, LA 49 begins at an intersection with US 61 (Airline Drive) east of the main entrance to Louis Armstrong New Orleans International Airport. It proceeds north as a divided, four-lane highway along Williams Boulevard through a largely residential neighborhood known as Kenner Heights. After , LA 49 intersects West Metairie Avenue opposite Kenner City Hall, and the median gives way to a center turning lane. Now flanked by commercial establishments, LA 49 continues north through the center of the Highway Park subdivision. After another , LA 49 intersects Veterans Memorial Boulevard, the principal east–west commercial thoroughfare of Kenner and neighboring Metairie. Here it widens to a divided, six-lane highway and remains in that capacity for the remainder of its route. It then immediately enters a complex interchange with I-10 at Exit 223A–B. I-10 heads toward Baton Rouge to the west and New Orleans to the east. Just north of the I-10 interchange, LA 49 intersects 32nd Street, which leads to the nearby Esplanade Mall. LA 49 continues north through intersections with West Esplanade Avenue and Vintage Drive as it passes alongside the Driftwood Park neighborhood. The route ends later at an intersection with a local road known as Joe Yenni Boulevard on the west and 44th Street on the east. Williams Boulevard continues north a short distance past the Pontchartrain Center, a large multi-purpose arena, to the Laketown recreation area and the Treasure Chest Casino on Lake Pontchartrain.〔〔〔 The route is classified as an urban principal arterial south of I-10 and an urban minor arterial north of I-10 by the Louisiana Department of Transportation and Development (La DOTD).
