[edit] Route description
In New Orleans, LA 46 begins as Elysian Fields Avenue at an intersection with LA 39 (North Claiborne Avenue) and LA 3021 (Elysian Fields Avenue). After heading south five blocks, LA 46 turns onto St. Claude Avenue and heads east. It crosses the Industrial Canal via the St. Claude Avenue Bridge and runs through the city's Lower 9th Ward, continuing to parallel to the Mississippi River. At the Orleans-St. Bernard Parish line, LA 46 becomes St. Bernard Highway. Serving as the southernmost west–east thoroughfare of the parish, it intersects LA 47 (Paris Road) and LA 3238 (Palmisano Boulevard) in Chalmette. Continuing eastward, the highway again meets LA 39 at Bayou Road and runs concurrently for two miles (3 km) near the end of East Judge Perez Drive, at which point LA 46 turns east through the community of Reggio and LA 300. From there, LA 46 connects to the towns of Yscloskey (via LA 625), Shell Beach, and Hopedale (via LA 624) before ending at a dead end with the Mississippi River-Gulf Outlet Canal.
LA 46 is a divided, four-lane highway from LA 39/LA 3021/North Claiborne Avenue to LA 47/Paris Road, where it narrows to an undivided, two-lane highway from LA 47/Paris Road to the westernmost interection of with LA 300/Bayou Road. The route again widens to four lanes and becomes a divided highway from the westernmost interection of with LA 300/Bayou Road to the easternmost intersection with LA 300/Bayou Road before narrowing again to an undivided, two-lane roadway from the easternmost intersection with LA 300/Bayou Road to the eastern terminus at Shell Beach.
