Mississippi Highway 7 (MS 7) runs generally north–south from the Tennessee state line in Benton County to Belzoni, Mississippi. It travels approximately 168 miles (270 km), serving Humphreys, Leflore, Carroll, Grenada, Yalobusha, Lafayette, Marshall, and Benton counties while serving several points of interest, including Florewood River Plantation State Park, the University of Mississippi, and Wall Doxey State Park. MS 7 runs nearly parallel to the rarely used Mississippi Central Railroad.
