Louisiana Highway 406 (LA 406) runs 6.00 miles (9.66 km) in a north–south direction from LA 23 in Belle Chasse, Plaquemines Parish to the junction of two local roads in New Orleans, Orleans Parish. It provides access to the Woodland Bridge across the Gulf Intracoastal Waterway for Belle Chasse and an area of New Orleans known as the Algiers Lower Coast.[10][11][12][13]

LA 406 heads north from LA 23 (Belle Chasse Highway) in Belle Chasse. Traveling along Woodland Highway, the route passes a series of newer residential subdivisions. The roadway curves to the northeast, traversing a corner of Orleans Parish, and passes a small cluster of industrial facilities located alongside the Gulf Intracoastal Waterway. LA 406 proceeds straight ahead and crosses from Plaquemines Parish again into Orleans Parish, simultaneously re-entering the New Orleans city limits. After crossing underneath the Woodland Bridge, LA 406 engages in a roundabout with LA 407, which loops around onto the bridge and across the waterway. The highway then passes the entrance to the upscale English Turn residential community and country club. LA 406 curves due east onto Patterson Drive (also known as River Road) along the Mississippi River levee and proceeds to an intersection with Stanton Road. River Road continues as a local road until reaching the U.S. Coast Guard station three miles (4.8 km) later.[10][11][12][13]

The divided four-lane highway loops to the north and proceeds across the high-level Woodland Bridge over the Gulf Intracoastal Waterway, located along the Orleans–Plaquemines parish line. Returning to grade, LA 407 intersects General de Gaulle Drive, which continues ahead through Algiers toward the Crescent City Connection bridge spanning the Mississippi River in Downtown New Orleans.

Louisiana Highway 426

Length7.390 mi[1] (11.893 km)

Louisiana Highway 426 (LA 426) runs 7.39 miles (11.89 km) in an east–west direction from LA 73 in Baton Rouge to US 190 between Baton Rouge and Denham Springs. The route is located entirely within East Baton Rouge Parish and is known locally as Old Hammond Highway.[4][16][41]

LA 426 heads east from LA 73 (Jefferson Highway) in Baton Rouge as an undivided four-lane highway. It intersects LA 1068 (Drusilla Lane) just before crossing US 61 (Airline Highway), where the roadway widens to include a center turning lane. Shortly before exiting the city limits, LA 426 narrows to two lanes at an intersection with Boulevard de Province. The route proceeds eastward and intersects LA 3245 (O'Neal Lane) before terminating at US 190 (Florida Boulevard) just west of the Amite River.[4][16][41]

LA 426 was the original traffic route between Baton Rouge and Denham Springs in the early 20th Century. Known as Benton's Ferry Road, it traveled from Jefferson Highway (formerly called Clay Cut Road) to Benton's Ferry on the Amite River near the present location of the US 190 crossing. The ferry service was replaced in 1918 by a bridge (which was in turn replaced by an improved bridge crossing in 1933). The highway was designated as part of State Route 7 in 1921, and it became part of the original alignment of US 190 in 1926. Both designations were removed from the route in 1942 when an extension of Florida Boulevard from Downtown Baton Rouge to the Amite River was completed. The road remained in the state highway system as State Route 7-D until becoming LA 426 in the 1955 Louisiana Highway renumbering.

As of 2018, LA 426 is under agreement to be removed from the state highway system and transferred to local control.[42]

The entire highway is in East Baton Rouge Parish.

Louisiana Highway 427 (LA 427) runs 14.57 miles (23.45 km) in a northwest to southeast direction from LA 73 in Baton Rouge, East Baton Rouge Parish to a second junction with LA 73 at Hope Villa, Ascension Parish. It is a busy suburban commercial and residential thoroughfare over most of its route and almost entirely parallels I-10.[4][16][43][44]

LA 427 heads south from LA 73 (Government Street) along South Acadian Thruway as an undivided four-lane highway. After passing through a diamond interchange with I-10 at exit 157B, the route turns southeast onto Perkins Road, gaining a center turning lane, and proceeds out of the Baton Rouge city limits. Intersections with several major thoroughfares connect with the interstate to the northeast, including LA 3064 (Essen Lane), LA 1248 (Bluebonnet Boulevard), and LA 3246 (Siegen Lane). The roadway narrows to two lanes after passing the latter junction and generally remains in that capacity for the remainder of the route. Just before it crosses into Ascension Parish, LA 427 briefly makes a jog onto LA 42 (Highland Road) through a second interchange with I-10 at Kleinpeter. The route then curves to the northeast at LA 928 (Bluff Road) and crosses US 61 (Airline Highway). Shortly afterward, LA 427 terminates at LA 73 (Old Jefferson Highway) south of Hope Villa, within the census-designated boundary of Prairieville.[4][16][43][44] As of 2018, the portion of LA 427 in Baton Rouge County is under agreement to be removed from the state highway system and transferred to local control.[45]

Existed1955–present

Louisiana Highway 428 (LA 428) runs 8.82 miles (14.19 km) from LA 23 near Belle Chasse to LA 407 in New Orleans. The route travels in an irregular direction and exists in two segments connected by local roads. The portion that travels on General de Gaulle Drive, however, is bannered east–west.[13][46][47]

LA 428 begins at a point on LA 23 (Belle Chasse Highway) between Belle Chasse and Gretna near the JeffersonPlaquemines parish line. It heads north on Behrman Highway, an undivided four-lane thoroughfare with a center turning lane. The highway crosses from Jefferson Parish into an area of New Orleans (co-extensive with Orleans Parish) known as Algiers. Just before the local name changes to Behrman Place, the center lane is replaced by a median, and the route proceeds to an intersection with General de Gaulle Drive. LA 428 turns west onto General de Gaulle Drive, a divided six-lane thoroughfare with a wide right-of-way that includes a drainage canal. The highway engages into a partial cloverleaf interchange with US 90 Bus. (Westbank Expressway). Approaching this junction, the westbound carriageway widens to five lanes to accommodate traffic exiting onto the Crescent City Connection into Downtown New Orleans.[12][13][46][48]

Passing through the interchange, the roadway narrows to a divided two-lane highway, and LA 428 soon crosses back into Jefferson Parish and enters the city of Gretna, where the local name changes to Burmaster Street. LA 428 then turns north onto Franklin Avenue at the northern terminus of LA 23 and remains a divided four-lane highway. The highway re-enters the city of New Orleans for a final time, and the local name changes to Nunez Street. LA 428 crosses underneath the Crescent City Connection on US 90 Bus. and engages into a roundabout with Mardi Gras Boulevard, a local road, at grade level between the two bridge spans. Shortly afterward, LA 428 turns to the northeast, and state maintenance ends at the five-point intersection of Lamarque, Vallette, and Verret Streets. Local traffic may travel north on Vallette Street and east onto Newton Street, where state maintenance resumes at an intersection with Behrman Avenue. Here, the roadway widens from two lanes to four lanes with a median and becomes known as General Meyer Avenue. LA 428 proceeds eastward to a terminus at LA 407 (Woodland Drive).[13][46][47][48]

As of 2019, a small portion in Jefferson County intersecting LA 23 is under agreement to be removed from the state highway system and transferred to local control.[49]
