Louisiana Highway 108 (LA 108) is a state highway located in western Calcasieu Parish, Louisiana that runs 24.8 miles (39.9 km) in a general west–east direction from Interstate 10 (I-10) in Vinton to U.S. Highway 90 (US 90) in Sulphur. The highway runs in roughly a "U" shape along section line roads, dipping southward from Vinton then east parallel to I-10 and back to the north toward Sulphur. The majority of the route is signed west–east except for the eastern leg running north to Sulphur, which is signed north–south. The latter section is also the most travelled, providing access to the oil and petrochemical industry south of Sulphur and a connection to LA 27.
From the west, LA 108 begins at an interchange with I-10 at Exit 8 in Vinton between the Texas-Louisiana state line and Sulphur. It proceeds east for 1.7 miles (2.7 km) to Gum Island Road then curves southward for another 3.0 miles (4.8 km) to Johnny Breaux Road. Here it curves back to the east, traveling 10.0 miles (16.1 km) and crossing a bridge over Bayou Choupique before reaching an intersection with LA 27 and LA 1133. LA 27 runs south into Cameron Parish while LA 1133 zigzags around the east side of Carlyss. LA 108 turns north, running concurrent with LA 27 for 3.2 miles (5.1 km) through Carlyss to an intersection with LA 1256, which heads due north to I-10 in Sulphur. From this intersection, LA 27 and LA 108 turn to the east, and LA 27 soon turns back to the north, also connecting with I-10 in Sulphur. LA 108 continues eastward, once again intersecting LA 1133, then turns north onto Cities Service Highway. After 1.3 miles (2.1 km), LA 108 crosses a bridge over Bayou D'Inde and enters Sulphur shortly thereafter. LA 108 enters into an interchange with I-10 and continues north for 1.4 miles (2.3 km) through the Maplewood area of Sulphur to a terminus at US 90 (East Napoleon Street).
