The portion of the current highway that runs east-west from near Patin Dyke to New Roads was the old LA State Route 135 portion.[27]
LA 413 heads north on Poydras Bayou Drive from LA 76 (Rosedale Road) in West Baton Rouge Parish. It crosses the concurrent US 190/LA 1 (Airline Highway) in Erwinville. The highway then skirts the Pointe Coupee Parish line for a short time before crossing it at a junction with LA 3091 (Flynn Road). LA 413 makes a brief zigzag onto LA 416 in Lakeland. Shortly afterward, the route turns west at an intersection with LA 414 (Island Road) and makes a long loop alongside False River through Jarreau and Dupont to Ventress. Here, LA 413 meets LA 414 (Ventress Road) a second time and turns north briefly to a junction with LA 415 (Patin Dyke Road) at Patin. The highway turns west once again and enters the city of New Roads, where it terminates at a junction with LA 1 Bus. at the corner of Main and New Roads Streets. LA 413 is an undivided two-lane highway for its entire length.[4][23][25][26]

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][42]
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][42]
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.[43]

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][44][45]
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][44][45] As of 2018, the portion of LA 427 in East Baton Rouge Parish is under agreement to be removed from the state highway system and transferred to local control.[46]

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][47][48]
LA 428 begins at a point on LA 23 (Belle Chasse Highway) between Belle Chasse and Gretna near the Jefferson–Plaquemines 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][47][49]
Passing through the interchange, the roadway narrows to a divided four-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, Verret, and Hermosa 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][47][48][49]
As of 2019, a small portion in Jefferson Parish intersecting LA 23 is under agreement to be removed from the state highway system and transferred to local control.[50]
