Interstate 155 (Missouri–Tennessee)


Interstate 155 is an east–west spur beginning in far southeast Missouri. The western terminus is south of Hayti, Missouri at Interstate 55, exits 17A and exit 17B. The route proceeds east where it crosses over the Mississippi River on the Caruthersville Bridge 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. It is the only road directly connecting Missouri and Tennessee.
US 412 overlaps the entire length of I-155.

History

Work on the Caruthersville bridge began in February 1969 and was completed on December 1, 1976. The last section of I-155 in Tennessee was completed in November 1979.
I-155 was once planned as Interstate 24W, and would have continued from Dyersburg southeast to Jackson, Tennessee; a similar route was built as a four-lane expressway in the 1990s and signed as part of US 412.

Future

The proposed extension of I-69 will intersect I-155 northwest of Dyersburg and replace the remainder of I-155 east of that point, reducing the length of I-155 by approximately.
