I-64 enters Illinois from St. Louis, Missouri, via the Poplar Street Bridge, where it overlaps I-55 as it crosses the Mississippi River. After crossing the city of [[East St. Louis, Illinois|East St. Louis]] and the rest of suburban [[St. Clair County, Illinois|St. Clair County]], the freeway heads southeast through rural [[Southern Illinois]]. Shortly after passing [[MidAmerica St. Louis Airport]] at exit&nbsp;23, I-64 enters [[Clinton County, Illinois|Clinton County]] and then [[Washington County, Illinois|Washington County]]. After providing access to towns such as [[Carlyle, Illinois|Carlyle]], [[Breese, Illinois|Breese]], [[Nashville, Illinois|Nashville]], and [[Centralia, Illinois|Centralia]], the freeway overlaps I-57 through the [[Mount Vernon, Illinois|Mount Vernon]] area for approximately {{Convert|5|mi|km|spell=in}}. East of Mount Vernon in Illinois, services along I-64 are slim to none. It is an almost completely flat and empty freeway, crossing [[Jefferson County, Illinois|Jefferson]], [[Wayne County, Illinois|Wayne]], and [[White County, Illinois|White]] counties as it progresses east toward Indiana and the [[Evansville, Indiana]], area. East of the St. Louis area, there are numerous oilwells dotting the landscape.
