The route has two distinct sections, the longer of which travels through Terrebonne Parish on either side of Bayou Terrebonne. It serves as the main highway through the city of Houma, which is also the parish seat. This portion of the highway is bannered east–west, though it runs primarily north–south. Southeast of Houma, LA 24 does assume an east–west trajectory as it turns away from Bayou Terrebonne and proceeds to the Lafourche Parish community of Larose, located at the junction of Bayou Lafourche and the Gulf Intracoastal Waterway.
