 Since that time, a large section of the route between the Gulf Intracoastal Waterway and Estelle has been bypassed for through traffic in favor of LA 3134 (Leo Kerner/Lafitte Parkway).This highway was constructed during the late 1970s on a new four-lane alignment running parallel to LA 45 and cutting across several of its curves.It was intended as the first link in the Lafitte-Larose Highway, a project that had been planned since at least 1930.
