This article is about the section of highway in Arkansas. For the entire length of highway, see Interstate 55
Interstate 55 (I-55) is a north–south Interstate Highway that has a 72.22-mile (116.23 km) section in the U.S. state of Arkansas connecting sections in Tennessee and Missouri. The route enters Arkansas on the Memphis & Arkansas Bridge over the Mississippi River from Memphis. It travels northward through northeast Arkansas connecting the cities of West Memphis and Blytheville. I-55 continues into Missouri heading to St. Louis, Missouri. The highway overlaps Interstate 40 in West Memphis and has a junction with Future Interstate 555, a spur route to Jonesboro, in Turrell. For the majority of its routing through Arkansas, I-55 generally follows U.S. Route 61 (US 61) through Arkansas.
I-55 enters Arkansas from Memphis, Tennessee on the Memphis & Arkansas Bridge over the Mississippi River, sharing the bridge with US 61/US 64/US 70/US 79. Shortly after entering the state the highway enters West Memphis, where US 70 exits the route and becomes Broadway Avenue. I-55/US 61/US 64/US 79 form a concurrency with Interstate 40 at exit 5, an overlap that lasts 3.1 miles (5.0 km). The highways split at I-40 exit 277, with I-40/US 63/US 79 continuing west to Little Rock and I-55/US 61/US 63/US 64 running north into Marion. US 64 exits I-55/US 61/US 63 in Marion, continuing west as Old Military Road toward Wynne. Interstate 55 continues to run through farmlands of the Arkansas delta, paralleling Highway 77 until Turrell.
Diagram of I-55 interchange#23, I-55/US 63/US 61 meets AR 77 and becomes I-555/US 63, I-55/US 61, and AR 77.
In Turrell, I-55/US 61/US 63 meets the southern terminus of Future I-555, a spur route of I-55 connecting Jonesboro to the Interstate Highway system. Future I-555/US 63 run north to Jonesboro, while Highway 77 and US 61 become frontage roads for I-55. Slightly east of this junction these frontage roads depart I-55, with Highway 77 running near Birdsong and US 61 serving Wilson. I-55 runs northeast to enter Mississippi County, Arkansas, having junctions with Highway 118 to Joiner, Highway 181 to Bassett, Highway 14 near Marie, and Highway 181 near Keiser. In Osceola, the route has a junction with Highway 140 near Osceola Municipal Airport. I-55 continues northeast, intersecting minor state highways in rural Mississippi County before a junction with US 61 in south Blytheville. Interstate 55 intersects Highway 18 in Blytheville before exiting town headed due north. The route has a junction with Highway 150 just before crossing the Missouri state line.
