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 next southern leg is the one from Texarkana to Fort Smith, AR - a 200-mile stretch estimated estimated to cost $3 billion. A short leg just south of Fort Smith to Alma, AR has already been designated as I-49. Though short, the segment has already sparked development at Chaffee Crossing near Fort Smith, as discussed in this article. 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.
