Louisiana Highway 122 (LA 122) is a state highway located in Grant Parish, Louisiana. It runs 26.10 miles (42.00 km) in an east–west direction from the junction of U.S. Highway 71 (US 71) and LA 1239-1 in Montgomery to LA 123 in Dry Prong.

The highway traverses a thickly forested area between the town of Montgomery and the village of Dry Prong, two small municipalities in Grant Parish, located in the central portion of the state. Along its route, LA 122 passes through the small rural communities of Hargis, Verda, and Faircloth. The eastern portion of the route between Lake Iatt and Dry Prong is largely located within the Kisatchie National Forest.

From the west, LA 122 begins at an intersection with US 71 in Montgomery, a small town in Grant Parish. The intersection is also a junction with LA 1239-1 (Old Jefferson Highway), a minor local route. LA 122 heads northeast from Montgomery into a thickly wooded rural area. Over the next seven miles (11 km), small clusters of homes sporadically line the highway at such points as the tiny community of Hargis. As it approaches the Winn Parish line, LA 122 curves to the southeast through the twin communities of Verda and New Verda. Here, the highway intersects LA 1240, which heads due south to a point on US 71 near Aloha. Shortly afterward, LA 122 begins a brief concurrency with LA 471, which heads north toward Winnfield, the seat of neighboring Winn Parish. Just beyond New Verda, LA 471 continues ahead to the south while LA 122 turns eastward onto an intersecting road.^[2][3][4]

The surroundings become more sparsely populated as the highway passes along the north side of Lake Iatt, which contains a game and fish preserve. About seven miles (11 km) beyond the turn-off, LA 122 curves sharply to the south before resuming an eastward course through an area known as Faircloth. The route then turns southeast into the Catahoula Ranger District of the Kisatchie National Forest. LA 122 winds its way through the piney woods for another 3.5 miles (5.6 km) before entering the village of Dry Prong. Traveling along Grove Street, the highway reaches its eastern terminus at a point on LA 123 located 0.2 miles (0.32 km) from a junction with US 167, connecting with Winnfield to the north and Alexandria to the south.^[2][4][5]

LA 122 is an undivided two-lane highway for its entire length.^[2] The highway is classified as a rural major collector by the Louisiana Department of Transportation and Development (La DOTD). Daily traffic volume in 2013 averaged between 800 and 1,040 vehicles.^[6] The posted speed limit is generally 55 mph (90 km/h), reduced as low as 35 mph (55 km/h) through populated areas.^[2]

State Route 162
Location	Grant Parish
Length	25.2 mi[7] (40.6 km)
Existed	1926–c. 1940s

In the original Louisiana Highway system in use between 1921 and 1955, the modern LA 122 was part of two largely concurrent routes. The majority of what is now LA 122 was originally part of State Route 162, an addition to the state highway system that was designated by an act of the state legislature in 1926.

Route 162. Beginning at a point on Route 99, five (5) miles North of Dry Prong to Verda, Louisiana, thence to Montgomery, Louisiana, over the Verda and Montgomery road.

— 1926 legislative route description^[8]

The route followed the modern LA 122 from Montgomery to Faircloth but rather than continuing into Dry Prong, it turned northeast onto what is now Parish Road 11 (Landfill Road) to a point on US 167 (pre-1955 State Route 99) near Williana.

State Route 475
Location	Montgomery–Dry Prong
Length	26.9 mi[9] (43.3 km)
Existed	1928–1955

Two years later, State Route 475 was established along the same alignment between Montgomery and Faircloth but with a terminus in Dry Prong rather than Williana.^[8]

Route 475. Beginning at Montgomery, intersecting the Jefferson Highway, running northeast via Verda, connecting with the Pershing Highway at Verda, thence in a southeasterly direction about one and one half mile, thence following the meanderings of the present graded road to a point on Iatt Lake to be designated by the La. Highway Commission, thence across said Iatt Lake via Hebron Church, following the meanderings of the present graded road as nearly as practicable to Dry Prong.

— 1928 legislative route description^[8]

As the more detailed legislative description for Route 475 indicates, Montgomery and Verda were located along the Jefferson Highway and Pershing Highway, respectively. These were two important auto trails that pre-dated the numbered U.S. Highway system. In 1926, US 71 was routed along the Jefferson Highway (State Route 1) through Montgomery, and US 167 was routed along the Pershing Highway (State Route 5) through Verda.^[10] The western portion of Route 162-475 that connected the new U.S. highways was gravelled around 1929.^[11][12] However, US 167 was shifted onto its present alignment through Dry Prong in 1932, allowing a more direct route between Alexandria and Winnfield.^[13][14] Soon afterward, the gravel road was extended eastward to Dry Prong along Route 475, which became the main traffic route, while the eastern portion of Route 162 between Faircloth and Williana remained unimproved.^[7] Route 162 was dropped from the state highway system prior to the 1955 Louisiana Highway renumbering, leaving the entire length between Montgomery and Dry Prong as Route 475 only.^[9] Paving of the Montgomery–Verda and Faircloth–Dry Prong sections of Route 475 was completed about 1954, leaving only the gap between Verda and Faircloth as a gravel road at the time of the renumbering.^[15][16]

LA 122 was created in 1955 as a direct renumbering of former State Route 475.^[a][16][17]

La 122—From a junction with La-US 71 at or near Montgomery through or near Verda and Faircloth to a junction with La 123 at or near Dry Prong.

— 1955 legislative route description^[17]

Since the 1955 renumbering, the route of LA 122 has remained virtually the same. Only minor changes have resulted from the smoothing of several curves over the years. The biggest improvement to the route occurred early on when the last section of gravel highway between Verda and Faircloth was paved around 1957.^[16][18]

The entire highway is in Grant Parish.
