It runs 20.61 miles (33.17 km) in a general north–south direction from a dead end at Lake Pontchartrain in Madisonville to a junction with LA 25 south of Folsom.

The route traverses the length of Madisonville, a small town in St. Tammany Parish, where it travels along the Tchefuncte River and is partially concurrent with LA 21.

In the future, the entire route is proposed for deletion as part of the Louisiana Department of Transportation and Development's ongoing Road Transfer Program.

A short distance later, LA 21 branches to the northeast toward the city of Covington, taking the main flow of traffic with it.

LA 1077 proceeds northward, and over the next three miles (4.8 km), the highway passes Madisonville Elementary School, crosses Brewster Road, and reaches a diamond interchange with I-12 at exit 57.

The surroundings become sparsely populated north of I-12, as fewer residential subdivisions are visible within the thick pine forest.

The roadway, locally known as Turnpike Road, also continues straight ahead signed as LA 1077 for less than 0.3 miles (0.48 km) until state maintenance ends at the St. Tammany–Tangipahoa parish line.

It ranges from a rural local road at either end to an urban minor arterial over the LA 21 concurrency in Madisonville.

By this time, the Louisiana Highway Commission (predecessor of the modern Department of Transportation and Development) had gained the authority to designate routes at its own discretion.

La DOTD is currently engaged in a program that aims to transfer about 5,000 miles (8,000 km) of state-owned roadways to local governments over the next several years.

[14] Under this plan of "right-sizing" the state highway system, the entirety of LA 1077 is proposed for deletion as it no longer meets a significant interurban travel function.
