Route descriptionEdit

In Mississippi, I-55 runs 290.5 miles (467.5 km) from the Louisiana border near Osyka to Southaven on the Tennessee border, just south of Memphis. The highway parallels US 51 during its trek roughly through the center of Magnolia State. North of Jackson, the Interstate runs east of the bluffs of the Mississippi Delta.

Near Summit and McComb, the interstate is concurrent with US 98 for five miles as it passes through the western side of the cities. I-55 then intersects US 84 near Brookhaven, and becomes concurrent with US 51 near Crystal Springs. In Jackson, the highway is concurrent with I-20 for three exits, and US 51 leaves the concurrency after I-55's concurrency with I-20 begins. I-55 continues north on the eastern side of Jackson, and meets the northern terminus of I-220 near Ridgeland. The highway then parallels US 51 until the U.S. route crosses over to the western side of the interstate in Grenada. I-55 intersects US 278 at Batesville, and it becomes concurrent with I-69 north of Hernando. The highway crosses the state line north of Southaven into Tennessee.
