I-64 enters Illinois running concurrently with I–55 and U.S. Route 40 (US 40) over the Mississippi River on the Poplar Street Bridge. After splitting from these highways in East St. Louis, I-64 turns southeasterly and proceeds through St. Clair County towards the Belleville area travelling through the eastern/southeastern St. Louis suburbs of Caseyville, Fairview Heights, O'Fallon, and Shiloh, where the interstate skirts the northern edge of Scott Air Force Base and MidAmerica St. Louis Airport and provides access to Mascoutah and Lebanon via IL Route 4. A new interchange at Rieder Road was completed in September 2017 to create better access to Scott Air Force Base. As part of the new interchange, a third lane in each direction, a wide left shoulder to accommodate a future fourth lane in each direction, and a center jersey barrier was added from one-mile west of Air Mobility Drive/IL Route 158 to Rieder Road.
At the St. Clair and Clinton county line, the Interstate passes the exurb of New Baden, after which it crosses the southern boundary of Clinton County and leaves the St. Louis metropolitan area. It then traverses a rural part of Illinois through Washington and Jefferson counties, which has no adjacent cities or major intersections passing it reaches the city of Mount Vernon in Jefferson County, where it has a short concurrency with I-57. Mount Vernon is the only major city and intersection served by I-64 in Illinois outside of the St. Louis metropolitan area. Past Mount Vernon, the Interstate enters another rural stretch through parts of Jefferson, Wayne, and White counties before crossing the Wabash River into Indiana.
