Louisiana Highway 3154 (
LA 3154) runs in a north–south direction from
LA 48 in
Harahan to
US 61 in
Metairie,
Jefferson Parish. 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 intersects
LA 3139 (
Earhart Expressway) and proceeds across the
Canadian 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 as
LA 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 the
Illinois 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. ==Louisiana Highway 3155==
