TheEarhart Expressway, named for formerNew Orleans Commissioner of Public Utilities,Fred A. Earhart,[1] is a state highway located in bothJefferson Parish andOrleans Parish,Louisiana. It is also designated asLouisiana 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 inNew Orleans. The expressway designation begins several blocks later as Earhart Boulevard transitions into alimited-access freeway after crossing Hamilton Street. Earhart Expressway proceeds westward and passes over Hoey's Canal and theCanadian National Railway (CN) as it crosses fromOrleans Parish intoJefferson Parish. A partial interchange at Deckbar Avenue provides access toU.S. 90 (Jefferson Highway). Continuing westward along the southern boundary ofMetairie, the expressway passes underneath Causeway Boulevard (LA 3046) and crosses over theNorfolk Southern Railway (NS). A second partial interchange is encountered at Cleary Avenue, providing access toU.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 theHuey P. Long Bridge with U.S. 61 andI-10. From this interchange, the expressway proceeds westward to a terminus at Dickory Avenue (LA 3154) nearHarahan.
The majority of the expressway carries three lanes in each direction, narrowing to two lanes at either end. The posted speed limit is 50 mph (80 km/h), and there is no paved shoulder along the route. Excepting the full interchange at Clearview Parkway, exits only occur from the westbound lanes, and marked on-ramps only serve the eastbound direction. (An unmarked on-ramp enters the westbound lanes from L&A Road behind theKansas City Southern railroad yard). Earhart Expressway is used as a relatively uncongested route for commuters, as well as an alternate to I-10 or Airline Drive to reachLouis Armstrong New Orleans International Airport.
The Earhart Expressway is an extension of Earhart Boulevard, a divided four- and six-lane thoroughfare that begins at Loyola Avenue near theNew Orleans Union Passenger Terminal. It continues the route of Calliope Street alongside and underneath thePontchartrain Expressway (U.S. 90 Business), splitting off atSouth Claiborne Avenue and following an abandoned railroad right-of-way to the beginning of the expressway, about 0.5 miles (0.80 km) from the Orleans/Jefferson Parish line.
