History In the original Louisiana Highway system in use between 1921 and 1955, the modern LA 52 was originally designated as part of State Route 2, which followed the Old Spanish Trail auto trail throughout the state of Louisiana. In 1926, it became part of the original route of US 90, which duplicated Route 2 throughout the state. In April 1941, US 90 was moved onto its current alignment between Boutte and the Huey P. Long Bridge, bypassing the winding River Road. Route 2 was moved along with it, and the former alignment through Luling carried the designation of Route 1092 until the 1955 Louisiana Highway renumbering. LA 52 was created with the 1955 renumbering, and its route has remained the same to the present day. Future La DOTD is currently engaged
