for I-310 are to relocate the southern end of the interstate to connect with the future extension of I-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 Avenue to I-310, to serve as a freeway alternative to I-10. 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.
