Louisiana Highway 611 (LA 611) is a collection of three current and ten former state-maintained streets in Jefferson, Metairie, and New Orleans.
LA 611-1 is known locally as River Road and is an undivided, two-lane highway for its entire length.
The route is known locally as Shrewsbury Road and is an undivided, two-lane highway for its entire length.
The route was severed in June 1957 when the railroad crossing on Shrewsbury Road was closed following completion of the parallel Causeway Boulevard (LA 3046) overpass.
Shrewsbury Road then became part of State Route 454 until the 1955 Louisiana Highway renumbering.
After briefly heading north on Severn Avenue, LA 611-9 immediately turns eastward onto Metairie Road, which is the local name for the remainder of its route.
With the exception of the block-long divided, four-lane section near Severn Avenue (configured in February 1957), LA 611-9 is an undivided, two-lane highway in Jefferson Parish.
In December 1916, the route of today's LA 611-9 was designated as the New Orleans entrance of the Jefferson Highway.
These highways were moved off of the route in 1928-1929 when Jefferson Highway was extended along the Orleans-Kenner interurban streetcar right-of-way from Shrewsbury Road to the Protection Levee at South Claiborne Avenue to provide a more direct entrance into New Orleans.
LA 48 eastbound traversed the remainder of Central Avenue northward to U.S. 61 (Airline Drive).
The route was severed in June 1957 when the railroad crossing on Labarre Road was closed following completion of the parallel Causeway Boulevard (LA 3046) overpass.
After an intersection with former LA 611-6 (Cicero Street), it continued northward to a terminus at U.S. 90 (Jefferson Highway).
LA 611-6 followed Cicero Street and was an undivided, two-lane highway for its entire length.
LA 611-7 followed Dakin Street and was an undivided, two-lane highway for its entire length.
LA 611-8 followed Monticello Avenue, running alongside the Jefferson Parish/Orleans Parish Line, and was an undivided, two-lane highway for its entire length.
LA 611-10 followed Clearview Parkway and was a divided, six-lane highway for its entire length.
LA 611-11 followed Transcontinental Drive and was a divided, four-lane highway for its entire length.
LA 611-12 followed Hickory Avenue and was an undivided, two-lane highway for its entire length.
LA 611-13 followed Little Farms Avenue and was an undivided, two-lane highway for its entire length.
