Interstate 310 (I-310) is a short spur route of I-10 west of New Orleans, located entirely in St. Charles Parish, Louisiana. It begins at a point on I-10 just west of Louis Armstrong New Orleans International Airport and the city of Kenner. It travels southward as an elevated freeway across the LaBranche Wetlands and intersects U.S. Route 61 (US 61) in St. Rose. The highway crosses the Mississippi River from Destrehan to Luling via the Hale Boggs Memorial Bridge. After a brief concurrency with Louisiana Highway 3127 (LA 3127), I-310 terminates at US 90 in Boutte.
