I-55 enters Arkansas from Tennessee as it crosses the Mississippi river. It overlaps I-40 for approximately 2.8 miles (4.5 km) in West Memphis. After separating from I-40, I-55 turns northward and runs to the Missouri border, via the intersection with the stretch of U.S. 63 that holds the future alignment of Interstate 555.
