I-49 in Arkansas is composed of three disconnected segments: northern, southern, and a short connector skirting [[Fort Smith, Arkansas|Fort Smith]] near Fort Chaffee designated as AR 549.

The southern segment of I-49 enters Arkansas from Louisiana. The short segment progresses northward to a temporary terminus at US&nbsp;71 and US&nbsp;59 at the Texas state line north of Texarkana.

The northern segment of I-49 in Arkansas, most of which was formerly signed as part of [[Interstate 540 (Arkansas)|I-540]], begins at [[Interstate 40 in Arkansas|I-40]] in [[Alma, Arkansas|Alma]] and runs north to [[Northwest Arkansas]] through the [[Boston Mountains]]. The freeway passes through steep, sparsely populated terrain before entering the [[Bobby Hopper Tunnel]] in [[Washington County, Arkansas|Washington County]]. Entering Northwest Arkansas, I-49 has seven exits for [[Fayetteville, Arkansas|Fayetteville]] and three exits for [[Springdale, Arkansas|Springdale]] before entering [[Benton County, Arkansas|Benton County]]. The route serves as the boundary between [[Bentonville, Arkansas|Bentonville]] and [[Rogers, Arkansas|Rogers]], with seven exits for the two cities. After an interchange with US&nbsp;71 just south of the Bentonville–Bella Vista city line, I-49 follows the Bella Vista Bypass, which runs to the south and west of [[Bella Vista, Arkansas|Bella Vista]] before crossing into Missouri.

I-49 is designated as the [[Boston Mountains Scenic Loop]] between Alma and Fayetteville. The I-49 designation replaced the I-540 designation through Northwest Arkansas in March&nbsp;2014,<ref>{{cite letter |first= Gregory G |last= Nadeau |title= Letter Approving I-49 Designation |recipient= Scott E.
