Interstate 310 (abbreviated I-310) is a short spur route of Interstate 10 near New Orleans, Louisiana, United States. It runs south from Interstate 10 near the New Orleans International Airport, intersects with U.S. Highway 61 and ends at the junction with U.S. Highway 90.

Interstate 310 crosses the Mississippi River via the Luling Bridge (Hale Boggs Memorial Bridge), a cable-stayed bridge connecting the towns of Luling and Destrehan. The bridge was completed in 1983, long before the rest of the freeway was built. The southernmost mile was originally built as part of Louisiana Highway 3127, an inland bypass to Louisiana Highway 18.

The final stretch of this highway, a two-mile bridge over environmentally sensitive wetlands between the US 61 interchange and the I-10 interchange, was completed on May 7, 1993. This section of the highway was constructed using a method known as "end-on construction". This is a top-down technique in which construction platforms are mounted on concrete piles to avoid disrupting the environment below. From these platforms, the next set of piles and bridge viaducts are placed, allowing the platform to progress forward for the next set.[1]

Interstate 310 was originally planned, along with Interstate 510, as part of Interstate 410, a southern beltway around the New Orleans metro area. With discussions of extending I-510 across the Mississippi River, there is speculation of reviving the idea of a connection between I-310 and I-510.

[edit] Future plans

Future plans for I-310 are to extend the southern end of the interstate to connect with the future extension of Interstate 49 from Lafayette to New Orleans. Another proposal in the Louisiana Statewide Transportation Plan proposes an extension of the Earhart Expressway (Louisiana Highway 3139) westward from Dickory Drive to Interstate 310 to serve as a freeway alternative to Airline Highway (US 61) and I-10.
