I-57 is the longest Interstate Highway in the state of Illinois, spanning {{Convert|364.16|mi|km}} long with Chicago being the main city along its northern route and Memphis being the southern main city along its southern route. I-57 then enters Illinois across the [[Mississippi River]] into [[Cairo, Illinois|Cairo]]. It passes through [[Mounds, Illinois|Mounds]] and [[Ullin, Illinois|Ullin]], and then it makes an interchange with [[U.S. Route 51 in Illinois|US&nbsp;51]], making US&nbsp;51 depart from its temporary concurrency with the Interstate. I-57 then continues north and has an interchange with [[Interstate 24 in Illinois|I-24]] toward [[Nashville, Tennessee]]. It then continues to head toward [[Marion, Illinois|Marion]], [[West Frankfort, Illinois|West Frankfort]], [[Benton, Illinois|Benton]], [[Whittington, Illinois|Whittington]], and [[Ina, Illinois|Ina]] and then heads into [[Mount Vernon, Illinois|Mount Vernon]].
