The Earhart Expressway, named for former New Orleans Commissioner of Public Utilities, Fred A. Earhart, is a state highway located in both Jefferson Parish and Orleans Parish, Louisiana. It is also designated as Louisiana Highway 3139 (LA 3139), spanning a total of 5.2 miles (8.4 km). Although it is an odd-numbered highway and is bannered north/south, it travels in a more east-to-west direction.

From the south (east), LA 3139 begins at the intersection of Earhart Boulevard and Monroe Street in New Orleans. The expressway designation begins several blocks later as Earhart Boulevard transitions into a limited-access freeway after crossing Hamilton Street. Earhart Expressway proceeds westward and passes over Hoey's Canal and the Canadian National Railway (CN) as it crosses from Orleans Parish into Jefferson Parish. A partial interchange at Deckbar Avenue provides access to U.S. 90 (Jefferson Highway). Continuing westward along the southern boundary of Metairie, the expressway passes underneath Causeway Boulevard (LA 3046) and crosses over the Norfolk Southern Railway (NS). A second partial interchange is encountered at Cleary Avenue, providing access to U.S. 61 (Airline Drive), after which the expressway again crosses over the CN railroad tracks as well as Central Avenue. The only full interchange along the route occurs at (South) Clearview Parkway (LA 3152), a north-south thoroughfare which connects the Huey P. Long Bridge with U.S. 61 and I-10. From this interchange, the expressway proceeds westward to a terminus at Dickory Avenue (LA 3154) near Harahan.
