Location	Jefferson Parish
Length	4.27 mi[1] (6.87 km)
Existed	1972–present

Louisiana Highway 3152 (LA 3152) is astate highway inLouisiana that servesJefferson Parish. LA 3152 spans 3.8 miles (6.1 km) in a south to north direction^[4] and is known locally asSouth Clearview Parkway andClearview Parkway.

Louisiana Highway 3153
Location	Metairie
Length	0.5 mi (800 m)
Existed	1972–1980s

Louisiana Highway 3153 (LA 3153) ran 0.5 miles (0.80 km) in a north–south direction along Transcontinental Drive fromUS 61 (Airline Highway) to West Metairie Avenue inMetairie,Jefferson Parish.^[5] It was a divided four-lane highway for its entire length.

Transcontinental Drive began as a main thoroughfare through the Bridgedale subdivision, which opened in 1925 during construction of the Airline Highway betweenShrewsbury andKenner. In 1930, it was designated as State Route 1246 in the pre-1955 Louisiana Highway system. Transcontinental Drive was intended to be extended south to Jefferson Highway (State Route 1) to connect with theHuey P. Long Bridge then in the planning stages. These plans never came to fruition, and the Bridgedale area would not be not directly connected to the bridge for almost fifty years via an extension of Clearview Parkway. State Route 1246 becameLA 611-11 in the1955 Louisiana Highway renumbering and assumed its present number in 1972. The route was returned to local control by 1986.

The entire highway was inMetairie,Jefferson Parish.

Louisiana Highway 3154
Location	Harahan–Metairie
Length	3.16 mi[1] (5.09 km)
Existed	1972–present

Louisiana Highway 3154 (LA 3154) runs 3.16 miles (5.09 km) in a north–south direction fromLA 48 inHarahan toUS 61 inMetairie,Jefferson Parish.^[6]

The route initially heads north on Hickory Avenue, an undivided two-lane thoroughfare, from LA 48 (Jefferson Highway) in Harahan. At Roberts Street, signs direct traffic onto Dickory Avenue, a parallel divided four-lane thoroughfare, to continue north on LA 3154. Officially, the route leaves Hickory Avenue further north via Gardner Street (also the connector for southbound traffic), requiring a U-turn before proceeding north on Dickory Avenue. Now outside the Harahan city limits, LA 3154 intersectsLA 3139 (Earhart Expressway) and proceeds across theCanadian National Railway (CN) tracks via an overpass into Metairie. The highway proceeds a short distance further to its terminus at US 61 (Airline Drive).

LA 3154 was designated asLA 611-12 prior to 1972, when five digit routes were eliminated by the state highway department. The route originally followed Hickory Avenue for its entire length and crossed what was then theIllinois Central Railroad (IC) line at grade. Construction began in 1974 on a four-lane bypass of Hickory Avenue that would include a railroad overpass and an interchange with the future Earhart Expressway. The new alignment, Dickory Avenue, opened in December 1975 and extended from Citrus Road to Airline Highway (now Airline Drive). Almost two decades later, Dickory Avenue was extended slightly to the south, providing better access to the Elmwood Business Park. In 2003, a further extension continued the road to its present terminus just south of 9th Street, providing another route into the Elmwood Business Park via an extension of Mounes Street. Plans are underway to extend the road to Jefferson Highway and bypass the remainder of Hickory Avenue.

The entire highway is inJefferson Parish.

Little Farms Avenue is the main thoroughfare of the J. H. Little Farms residential subdivision opened in 1925.^[8] The subdivision was laid out alongside theJefferson Highway (State Route 1 in the pre-1955 Louisiana highway system) and adjacent streetcar line operated by the Orleans-Kenner Traction Company. Little Farms Avenue was soon extended across the railroad tracks to connect with the newly constructed Airline Highway.^[9] In 1954, the Bunche Village residential subdivision opened adjacent to Little Farms Avenue between the railroad tracks and Airline Highway.^[10]

Little Farms Avenue was originally designated as State Route 2220 in the pre-1955 system and included the entire length of the road from Jefferson Highway to Airline Highway (now Airline Drive). It becameLA 611-13 in the1955 Louisiana Highway renumbering, but in 1972, the route was renumbered to LA 3155^[11] and retained only the section of Little Farms Avenue north of the railroad tracks.

The entire highway is inJefferson Parish.
