Louisiana Highway 46 (LA 46) is a state highway in Louisiana that serves Orleans and St. Bernard Parishes. It runs a west to east direction for a total length of 29.5 miles (47.5 km). It is demarcated as Elysian Fields Avenue and St. Claude Avenue in the city of New Orleans and as St. Bernard Highway, Bayou Road, East Judge Perez Drive, Florissant Highway and Yscloskey Highway in St. Bernard Parish. The highway is recognized by the United States Department of Transportation as San Bernardo Scenic Byway.
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.
