Entering Houma proper, LA 24 turns eastward, maintaining its path flanking Bayou Terrebonne. The highway passes through the city's historic downtown area and intersects LA 182, the pre-freeway alignment of US 90. LA 182 runs concurrent with LA 24 for two blocks as it zigzags from Barrow Street onto New Orleans Boulevard. Eastbound LA 182 still provides the most direct connection from Downtown Houma toward New Orleans, as US 90 now bypasses the city. Immediately east of New Orleans Boulevard, LA 24 crosses a high-level twin-span bridge over the Gulf Intracoastal Waterway. Returning to grade, LA 24 narrow to an undivided two-lane highway, as Main Street begins to carry two-way traffic at an intersection with LA 57 (Grand Caillou Road). At this point, westbound LA 24 traffic crosses from the south side of Bayou Terrebonne to the north side by way of a vertical lift bridge at the LA 57 junction. Park Avenue continues downstream as LA 659, also carrying two-way traffic across the bayou from LA 24.
