Louisiana Highway 483 (LA 483) runs 16.46 miles (26.49 km) in a north–south direction from US 171 in Noble, Sabine Parish to LA 175 in Pelican, DeSoto Parish.[35]

The route heads northeast from US 171 in Noble and curves due north at Sardis. Reaching Oak Grove, a point east of Converse, LA 483 turns east in a brief concurrency with LA 174 before resuming its northward course at Mitchell.[9][35][36] It proceeds in a general northeast direction and encounters a series of curves as it crosses from Sabine Parish into DeSoto Parish. Soon after crossing the parish line, LA 483 heads due north again and intersects LA 512. It immediately curves northeast into the small community of Pelican where it intersects LA 513. LA 483 proceeds a short distance to its terminus at LA 175 on the east side of town. It is an undivided two-lane highway for its length.[35][37][38]

Louisiana Highway 490 (LA 490) runs 14.96 miles (24.08 km) in a general east–west direction from a local road in Janie to the Red River east of Marco, Natchitoches Parish.[45]

LA 490 is an undivided, surfaced two-lane highway that continues the path of a dirt local road northeast through Janie. In Chopin, the highway passes through a diamond interchange with I-49 (exit 113) and crosses the Union Pacific Railroad line at grade. It then passes the entrance to the Martco lumber factory and crosses over the Cane River. At a T-intersection with LA 1, LA 490 turns southeast and runs concurrent with that highway for 2.4 miles (3.9 km) and crosses the Cane River a second time. LA 490 turns northeast off of LA 1 and winds through Galbraith and Marco, intersecting LA 3279 between those points. At the end of its route, LA 490 provides access to, and makes a loop in front of, the Red River Lock & Dam #3.[45][46][9]

For a time, LA 490 resumed on the opposite bank of the Red River in Colfax, following Faircloth and 2nd Streets to a junction with LA 8.[47] A spur continued along Faircloth Street past 2nd Street to a junction with LA 158. Prior to the 1930s, the two segments of LA 490 were connected by the West End Ferry.[48][49] During this time, LA 490 was designated as State Route 431 in the original state highway system, which was in use from 1921 to 1955.[48]

The entire highway is in Natchitoches Parish.
