Interstate 55 (I-55) is a north–south Interstate Highway that has a 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.
