Interstate 155 (I-155) is an east–west spur beginning in far southeast Missouri. The western terminus is south of Hayti, Missouri at Interstate 55, exits 17A (Interstate 55 northbound) and exit 17B (Interstate 55 southbound). The route proceeds east where it crosses over the Mississippi River from Caruthersville, Missouri, connecting with Dyersburg, Tennessee. Interstate 155 continues east before terminating at US 51, where US 412 continues its route south towards Jackson, Tennessee.
US 412 overlaps the entire length of I-155.
I-155 was once planned as Interstate 24W, and would have continued from Dyersburg southeast to Jackson, Tennessee; [ verification needed] a similar route was built as a four-lane expressway (with interchanges at most of the major intersections) in the 1990s and signed as part of US 412.
