Louisiana Highway 574 (LA 574) is a collection of eight current and four former state-maintained streets in Grand Isle, located in lower Jefferson Parish. All twelve routes were established with the 1955 Louisiana Highway renumbering.

Louisiana Highway 574-1 (LA 574-1) spans 0.66 miles (1.06 km) from south to north along Central Avenue. While in the Grand Isle city limits, the route is actually on Cheniere Caminada, the last part of the mainland approaching the bridge to Grand Isle. Ending at dead ends in both directions, LA 574-1 crosses LA 1 immediately to the west of the Caminada Pass bridge.

The entire highway is in Grand Isle, Jefferson Parish.
