Interstate 310 marker

Interstate 310 (I-310) is a short spur route of I-10 west of New Orleans, located entirely in St. Charles Parish, Louisiana, United States.

I-310 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. Highway 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.

I-310's southern terminus is at US 90, where it travels north through flat marshlands. The southernmost mile was originally built as part of LA 3127, an inland bypass to LA 18, and is cosigned with I-310. North of I-310's first interchange, LA 3127 leaves the Interstate, as I-310 heads towards the Mississippi River. After the next interchange, LA 18, I-310 crosses the Mississippi River via the Hale Boggs Memorial Bridge (Luling-Destrehan Bridge), a cable-stayed bridge connecting the towns of Luling and Destrehan.
