West of Baton Rouge, the current alignment generally follows the same route since its extension into Texas in 1935. The only major re-routing was between Deridder and Elton, where the original route followed LA 26. The portion between Oberlin and Elton was re-routed in 1937 to follow US 165 to Kinder before assuming the current alignment between Deridder and Kinder the following year. Other differences from the current route are as follows: LA 110 through Merryville; LA 3099 into DeRidder; LA 3253, 1244, 31, and 742 between Opelousas and Port Barre; Old U.S. 190 between Bayou Courtableau and Krotz Springs and between East Krotz Springs, Louisiana Krotz Springs and Lottie; LA 77 between Livonia and Rosedale; and LA 76 between Rosedale and Port Allen.
