The Earhart Expressway, named for Frederick Earhart, is a state highway located in both Jefferson Parish and Orleans Parish, Louisiana. It is also designated as Louisiana Highway 3139 or LA 3139. Although it is an odd-numbered highway and it is bannered north/south, it travels in a more east-to-west direction.

Earhart Expressway travels 4.82 miles (7.76 km) between LA 3154 (Dickory Avenue) in Jefferson Parish and Monroe Street in New Orleans. In Jefferson Parish, Earhart Expressway is a limited-access freeway, with three lanes in each direction, although with no paved shoulder. A full interchange occurs at LA 3152 (Clearview Parkway); otherwise, exits only occur from the west-bound lanes, and marked on-ramps only serve the east-bound direction (an unmarked on-ramp enters the westbound lanes from L&A Road behind the Kansas City Southern railroad yard). The posted speed limit is 50 mph (80 km/h) along the winding route. Once it enters Orleans Parish, Earhart Expressway changes into Earhart Boulevard and becomes a divided, four lane street. The Expressway is used as a relatively uncongested route for commuters, as well as an alternate to Interstate 10 or Airline Drive to reach New Orleans International Airport.
In Orleans Parish, Earhart loses its expressway designation at Monroe Street., which is about 0.5 miles (0.80 km) from the parish line. However, Earhart Boulevard continues eastward towards Downtown until it intersects with South Claiborne Avenue, where it becomes Calliope Street.
