Interstate 24 (I-24) is an Interstate Highway in the Midwestern and Southeastern United States. It runs diagonally from Interstate 57 (10 miles south of Marion, Illinois) to Chattanooga, Tennessee, at Interstate 75. As an even-numbered Interstate, it is signed as an east-west route, though the route follows a more southeast-northwest routing.

Because the routing of I-24 is diagonal, the numbering is a bit unusual as it does not completely follow theInterstate Highway System numbering conventions.

I-24 makes up the majority of a high-traffic corridor between St. Louis, Missouri, and Atlanta. This corridor utilizes Interstate 64 and Interstate 57 northwest of I-24, and Interstate 75 southeast of I-24.
