The primary benefits of I-49 are connecting population centers and economic growth. For every $1 billion in Interstate development, an estimated 49,000 jobs are created. Texarkana is expected soon to be criss-crossed by three interstates - I-30, I-49 and I-69 now being developed in Texas with segments already in Northwestern Mississippi and Tennessee.
As discussed by this original I-49 extension post, the segment from Lafayette, Louisiana to New Orleans is yet to be completed. Much of the Interstate will follow US 90, a majority of which is already limited access. The route is important to industry, particularly the petroleum industry. Texarkana, with a population of just 68,000 divided evenly between Texas and Arkansas, is already served by I-30 (itself suggested for extension). Nonetheless, officials see the new Interstate as a boon for economic development.

The Arkansas portion represents 315 miles for the full 1,700 mile Palms to Pines highway.
I-49 is expected have an intersection with the proposed Georgia to Texas Interstate-14, already under way in Texas, in Alexandria, LA.
