The route travels through a sparsely populated area along the east bank levee of the Mississippi River opposite the town of White Castle.

After passing in front of the Gillis W. Long Center, state maintenance ends, and a private gravel road continues around the bend in the river known as Point Clair.

[1][2] LA 141 is an undivided two-lane highway for its entire length and has a posted speed limit of 45 mph (70 km/h) between the former ferry landing and the end of state maintenance.

The route remained largely the same prior to the 1955 Louisiana Highway renumbering, experiencing only minor alterations due to reconstruction of the river levee.

The middle section of the route containing a gravel surface was removed from the state highway system by the 1990s and today runs through private property.

[15] Under this plan of "right-sizing" the state highway system, the northern segment of LA 141 is proposed for deletion as it does not meet a significant interurban travel function.
