Interstate 49 runs north from Lafayette to Shreveport and from Shreveport to Texarkana, Arkansas. Work on the southeastern extension to the New Orleans area is still underway. The Inner City Connector between I-20/49 in Shreveport and I-49/220 at North Shreveport also remains planned.
Upgrades to Interstate standards along U.S. 90 in the vicinity of New Iberia are ongoing. Plans for I-49 include extending the Westbank Expressway (Interstate 910 / U.S. 90 Business) westward and constructing a new corridor through the city of Lafayette.

The Interstate 49 main line originally ended at Interstate 20 west of Downtown Shreveport. Following completion of the last section of I-49 north from I-220 on October 17, 2018, I-49 was designated along a combination of I-20 west to LA 3132 and I-220 east as approved by AASHTO in 2019. The freeway resumes northward from I-220 at North Shreveport to Texarkana, Arkansas.
The Inner Loop Expressway (LA 3132) spurs east from I-49 to LA 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.
