Route description

Beginning at Mansfield through Benson, Converse, Noble, Zwolle, Many, Florien, Gandy, Hornsbeck, Leesville, De Ridder, Fulton, Lake Charles, thence following the Gerstner Field Road to Cameron Parish line, thence through Creole to Cameron. - 1924 Louisiana Legislative Route Description

From the south, LA 42 began at the town of Cameron, traveling north through prairie and marshes to Lake Charles, where LA 42 met LA 2/US 90. LA 42 picked up the US 171 designation, following a hilly road north out of Calcasieu Parish.

LA 42 then met LA 7, picking up the US 190 designation, carrying it north to an intersection with LA 22, where US 190 spun off to the west. LA 42 then entered Vernon Parish, meeting LA 21 and LA 39 before meeting LA 6 in Many.

After Many, LA 42 crossed paths with the two auxiliary routes, LA 42-D and LA 42-E, before ending in Mansfield at an intersection with LA 9/US 84.
