[8] It is currently proposed for deletion as part of La DOTD's Road Transfer program.

[19] The route's mileposts increase from the northern end contrary to common practice.

It heads north on Vincent Road to a point on LA 92 located about two miles (3.2 km) south of the village of Mermentau.

At this junction, LA 92 turns east from Mermentau Cove Road onto West Whitney Street.

[20] LA 1119 was created in the 1955 Louisiana Highway renumbering,[21] and its route has remained the same to the present day.

[24] The route's mileposts increase from the northern end contrary to common practice.

[25] The route begins on LA 100, which closely follows the north side of I-10 between Crowley and Egan.

From this junction, located about one mile (1.6 km) west of the Crowley city limit, LA 1121 heads north on Oro Trail Road and proceeds to a junction with LA 13 north of town.

[22][23] The main purpose was served for a quicker route for LA-100 users to merge onto North LA-13, but it is now currently proposed for deletion as part of La DOTD's Road Transfer program.

[29] The route primarily follows a rural section line road south of and parallel to US 90.

It has a brief concurrency with LA 26, which connects with Jennings to the north and Lake Arthur to the south.

[33] The route's mileposts increase from the northern end contrary to common practice.

Louisiana Highway 1138 (LA 1138) consists of three road segments with a total length of 4.88 miles (7.85 km) that are located in the Calcasieu Parish city of Lake Charles.

Approximately half the mileage is currently proposed for deletion as part of La DOTD's Road Transfer program.

[37] Routes deleted since the 1955 Louisiana Highway renumbering include: Louisiana Highway 1139 (LA 1139) ran 2.1 miles (3.4 km) in a north–south direction from LA 27 west of Iowa to a local road northwest of Iowa.

Once part of the main highway running along the Gulf of Mexico through Cameron Parish, this section of roadway was severed from the mainland in the mid-1940s when the Calcasieu Ship Channel was dug across its right-of-way.

[44][45] This bypassed a sharp bend in Calcasieu Pass and created what became known as Monkey Island.

A second ferry crossing was necessary to carry automobile traffic through Cameron until the highway was re-aligned to the north of the island around 1954.

[48] Discontinuation of the service had been threatened for several years when, in 2005, Hurricane Rita destroyed all structures on Monkey Island, displacing its residents and forcing the ferry's abandonment.

As of 2017, LA 1141 remains in the state highway system though the roadway is heavily damaged and mostly inaccessible.

After 0.3 miles (0.48 km), LA 1145 curves slightly northeast and maintains this heading for the remainder of its length.

[55] LA 1145 was created in the 1955 Louisiana Highway renumbering, and its route has remained the same to its present day.

[62] The route's mileposts increase from the eastern end contrary to common practice.

Louisiana Highway 1149 (LA 1149) ran 10.1 miles (16.3 km) in a southwest to northeast direction from a local road at the Jefferson Davis–Allen in Indian Village to US 165 in Kinder.
