Louisiana Highway 47 marker

Louisiana Highway 47 (LA 47) is a state highway located in southeastern Louisiana. It runs 15.91 miles (25.60 km) in a general southeast to northwest direction from the Mississippi River levee in Chalmette to the intersection of Hayne Boulevard and Downman Road in New Orleans.

LA 47 makes the shape of the number "7" and begins as a north–south route that travels along Paris Road through Chalmette, an unincorporated suburb of New Orleans and the seat of neighboring St. Bernard Parish. North of Chalmette, LA 47 crosses a high-level bridge over the Gulf Intracoastal Waterway and transitions to a controlled-access freeway that doubles as Interstate 510 (I-510). This stretch contains interchanges with both I-10 and U.S. Highway 90 (US 90), two major routes heading east out of New Orleans. The above segments of LA 47 serve not only as the primary north–south thoroughfare through Chalmette but also provide a vital hurricane evacuation route for residents of St. Bernard Parish and the east bank portion of Plaquemines Parish.

LA 47 was designated in the 1955 Louisiana Highway renumbering, replacing former State Route 61. North of I-10, the route turns west along the shore of Lake Pontchartrain and follows Hayne Boulevard from Little Woods to a point near the New Orleans Lakefront Airport. This portion of the route is an unsigned extension that came under state maintenance during the late 1970s.
