Much of LA 6 between Many and Natchitoches was reconstructed around the 1970s, straightening several sharp curves and zigzags. Fragments of the original route surviving today as local roads include: Shawnee Town Loop northeast of Many; Stoker Loop immediately northeast of Fort Jesup; Stewart Loop and Clower Loop between Fort Jesup and Robeline; Parish Road 648 (Johnny Floyd Road) northeast of Robeline; and Parish Road 542 (Old LA 6) on the west side of I-49. Two additional segments are still part of the state highway system. The first, LA 3118, serves the bypassed Fort Jesup State Historic Site. The second, LA 3278, is located at the west end of Natchitoches adjacent to I-49.
