The eastern terminus of LA 92 is located just within the corporate limits of Youngsville, a suburban city south of Lafayette.

This eastern segment became LA 92-1 in 2013 when much of the route within Youngsville was transferred to the city following a highway improvement project, which created a gap in state maintenance.

[2][4][5] Heading east from Maurice, LA 92 crosses a vertical lift bridge over Bayou Vermilion and into the small Lafayette Parish community of Milton.

The highway proceeds 2.9 miles (4.7 km) further to a roundabout junction with LA 339 (Verot School Road) at the western edge of Youngsville, a small suburban city.

[10] The route was straightened by utilizing parallel section line roads taken into the state highway system after the 1955 renumbering.

The eastern terminus was extended slightly from LA 31 at Cinco when a swing bridge was constructed across Bayou Teche in 1984.

[1] 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 portion of LA 92 between Maurice and Youngsville is proposed for deletion as it no longer meets a significant interurban travel function.

It was part of LA 92 until a portion of the route in Youngsville was transferred to local control in 2013, creating a gap in state maintenance.

From the west, LA 92-1 begins at the junction of Young Street and Larrivere Road near the eastern edge of Youngsville in Lafayette Parish.

The route proceeds a short distance further across a swing bridge spanning Bayou Teche to a terminus at LA 347 (Cemetery Road) on the opposite bank.

It is generally classified as a rural major collector by the Louisiana Department of Transportation and Development (La DOTD).
