Louisiana Highway 22 (LA 22) is a state highway located in southeastern Louisiana. It runs 71.15 miles (114.50 km) in a general east–west direction from the junction of LA 75 and LA 942 in Darrow to U.S. Highway 190 (US 190) in Mandeville.

The route traverses a variety of terrain and surroundings over the course of its journey, which begins at the Mississippi River in rural Ascension Parish. It also crosses several navigable waterways with movable bridges spanning two of them: the Amite River and Tchefuncte River. After crossing both Interstate 10 (I-10) and US 61 in Sorrento, LA 22 winds through a cypress swamp in Livingston Parish west of Lake Maurepas.

Near the town of Springfield, the highway enters the thick pine forest characterizing the north shore of Lake Pontchartrain and intersects the concurrent I-55/US 51 in Ponchatoula. On its east end, LA 22 becomes a heavily traveled residential and commercial corridor in suburban St. Tammany Parish between Madisonville and Mandeville. This stretch runs south of the parallel I-12 corridor and feeds traffic onto US 190 and the Lake Pontchartrain Causeway to the New Orleans area.

After crossing both Interstate 10 (I-10) and US 61 in Sorrento, LA 22 winds through a cypress swamp in Livingston Parish west of Lake Maurepas.

Near the town of Springfield, the highway enters the thick pine forest characterizing the north shore of Lake Pontchartrain and intersects the concurrent I-55/US 51 in Ponchatoula.

This stretch runs south of the parallel I-12 corridor and feeds traffic onto US 190 and the Lake Pontchartrain Causeway to the New Orleans area.

LA 22 was designated in the 1955 Louisiana Highway renumbering, replacing portions of five shorter former routes. These included State Route 761, State Route 54, State Route 160, State Route 122, and State Route 465. In its early years, LA 22 extended across the Mississippi River by ferry to Donaldsonville prior to the existence of the nearby Sunshine Bridge. The route was also much shorter on its eastern end, terminating at a junction with US 51 and US 190 in Ponchatoula until the latter was re-routed through Covington.

Route description
Darrow to Sorrento
From the west, LA 22 begins at a junction with LA 75 and LA 942 at the east bank levee of the Mississippi River opposite the city of Donaldsonville. The route heads northeast from the small Ascension Parish community of Darrow as an undivided two-lane highway, traveling through Hillaryville across the Canadian National Railway (CN) line and to the rear of Houmas House Plantation and Gardens. In Burnside, LA 22 intersects LA 44 and passes through a growing suburban area amidst the rural surroundings.[2][3][4]

Entering the town of Sorrento, the highway intersects LA 70, which leads across the Sunshine Bridge to Donaldsonville. Shortly afterward, LA 22 widens to a divided four-lane highway and passes through a diamond interchange with I-10 at exit 182, connecting with Baton Rouge and New Orleans. LA 22 continues along John Leblanc Boulevard, which largely bypasses the populated portion of the town. The highway crosses the Kansas City Southern Railway (KCS) line, followed closely by US 61 (Airline Highway), which parallels the interstate between the aforementioned cities. [2][3][4]

Sorrento to Lake Maurepas swamp
Narrowing back to two-lane capacity, LA 22 proceeds north from Sorrento to a T-intersection with LA 429 just east of St. Amant. It then turns due east briefly through an area known as Acy. Resuming its northeastern trajectory, LA 22 begins to wind its way through the swampland that surrounds Lake Maurepas. The highway crosses a bridge over the wide Amite River Diversion Canal, which is lined by boat houses and fishing camps.[2][3][4]

Continuing into Livingston Parish, LA 22 turns eastward at a T-intersection marking the terminus of LA 16 south of French Settlement. LA 16 leads to Denham Springs and Walker, the most populated areas of the parish, located along I-12. LA 22 follows a serpentine path through several small communities along the Amite River, such as Head of Island, Whitehall, and Maurepas. Curving again to the northeast, LA 22 crosses the river via swing bridge and passes through Killian, located at a junction with LA 444. The route then proceeds across a higher and longer bridge spanning the Tickfaw River, allowing a splendid view of the surrounding cypress swamp.[2][5][6]

Springfield and Ponchatoula
Entering the small town of Springfield, LA 22 turns northwest briefly at a T-intersection with LA 1037 (Collum Road). The two routes proceed along the town's main street in a wrong-way concurrency until reaching Walnut Street. From this four-way intersection, LA 1037 turns west toward Tickfaw State Park, LA 42 begins and proceeds along the main street, while LA 22 turns east across the Natalbany River into Tangipahoa Parish.[2][5][6]

Immediately across the parish line, LA 22 intersects LA 1249, which heads north through Pumpkin Center to a junction with I-12. For the remainder of its journey, LA 22 travels about two to three miles (3.2 to 4.8 km) to the south of I-12, the main east–west highway through the Florida Parishes on the north shore of Lake Pontchartrain. With the terrain having transitioned from swampland to pine forest, the surroundings become more consistently populated as LA 22 heads into the small city of Ponchatoula. On the outskirts of town, LA 22 widens to four lanes as it passes through a full cloverleaf interchange with the concurrent I-55/US 51, Route map:
