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.

This is a top–down technique in which construction platforms are mounted on concrete piles to avoid disrupting the environment below.
