As the above description indicates, Route 50 departed from the modern LA 9 at Creston and followed what is now LA 156 northeast to Goldonna. The route remained generally the same throughout the pre-1955 era with minor straightening of the roadway evident in several spots. The portion of Route 50 between Campti and Creston was graveled by 1927 and paved in 1949. The remainder of the route between Creston and Goldonna was graveled in 1928 but was not paved until after the 1955 Louisiana Highway renumbering.
