[edit] Route description
From the west, LA 48 begins at an intersection US 61 (Airline Highway) in Norco. Then known as Apple Street, it runs southward. When it reaches the Mississippi River, it turns eastward to follow and run parallel to it as River Road. It intersects LA 627, Interstate 310, LA 626, and LA 50 as it continues downriver through the St. Charles Parish communities of Destrehan, St. Rose, and Almedia. As it enters Jefferson Parish and Kenner, it becomes known as Jefferson Highway. After passing through Harahan, LA 48 shortly merges with US 90 at the east bank base of the Huey P. Long Bridge and Clearview Parkway. At Central Avenue, LA 48 turns northward and ends at an intersection with US 61.
LA 48 is an undivided, two-lane highway from US 61 to just west of Interstate 310, where it briefly divides and expands to four-lanes. The highway again becomes an undivided, two-lane route just east of Interstate 310 and continues in said configuration to near Williams Boulevard in Kenner. Here, the road divides and expands to four lanes once more unitl Central Avenue in Jefferson, where it reverts back to an undivided, two-lane roadway from Jefferson Highway to US 61.
