Interstate 49 between Shreveport and Lafayette is now complete. Extensions to the New Orleans area to the south and the Arkansas State Line to the north are still underway. Presently U.S. 90 is seeing an upgrade to Interstate standards between Berwick and Houma and again in the vicinity of New Iberia. Plans for Interstate 49 include upgrading the remainder of the Westbank Expressway (Interstate 910 / U.S. 90 Business) and constructing a new corridor through the city of Lafayette.

The Interstate 49 main line concludes at Interstate 20 west of Downtown Shreveport. The freeway resumes from Louisiana 1 northward to Texarkana, Arkansas, with construction to link that segment with Interstate 220 underway through 2018. Upon completion, Interstate 49 will shift to Louisiana 3132 (Inner Loop Expressway) and the western portion of I-220 to complete the route. This route may be temporary, as separate plans under study call for the continuation of I-49 north from I-20 to I-220 directly through north Shreveport. If this corridor is not built, the section of I-49 north from LA 3132 to I-20 will have to be renumbered.
The Inner Loop Expressway (Louisiana 3132) spurs east from I-49 to Louisiana 523 at Flournoy Lucas. The City of Shreveport, MPO and funding will determine the extension of the Inner Loop beyond this point.1 One possibility is to lengthen the freeway southeast to the planned I-69 corridor.
