Interstate 64 in Illinois

File:Poplar Street Bridge KM.jpg

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 traveling through the eastern/southeastern St. Louis suburbs of Caseyville, Fairview Heights, O'Fallon, and Shiloh. In Shiloh, the Interstate skirts the northern edge of Scott Air Force Base and MidAmerica St. Louis Airport and provides access to Mascoutah and Lebanon via Illinois Route 4 (IL 4). A new interchange at Rieder Road was completed in September 2017 to create better access to Scott Air Force Base.{{cite news |first = Kelsey |last = Landis |date = September 8, 2017 |url = https://www.bnd.com/news/local/article171738807.html |title = After Nearly Three Years of Construction, New Exit off Interstate 64 Will Open Soon |work = Belleville News-Democrat |access-date = November 25, 2018 }} 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 {{Convert|1|mi|km|spell=in}} west of Air Mobility Drive/IL 158 to Rieder Road.

At the St. Clair–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.{{cite map |author = Illinois Department of Transportation |date = November 2008 |url = http://www.dot.il.gov/maps/ExitNo.pdf |title = Interstate Exit Numbers of Illinois |scale = Scale not given |location = Springfield |publisher = Illinois Department of Transportation |access-date = August 2, 2014 |archive-date = May 29, 2010 |archive-url = https://web.archive.org/web/20100529054932/http://www.dot.il.gov/maps/ExitNo.pdf |url-status = dead }}{{google maps |url = https://www.google.com/maps/dir/38.6179689,-90.1825963/38.2284972,-87.9848868/@38.7041652,-89.4303714,9z/data=!4m3!4m2!1m0!1m0 |title = Overview Map of Interstate 64 in Illinois |access-date = August 2, 2014 }} Past Mount Vernon, the Interstate enters another rural stretch through parts of Jefferson, Wayne, and White counties before crossing the Wabash River into Indiana.

Starting in 1970, a small portion of I-64 opened just west of the Indiana state line.{{Illinois road map |year = 1970 |access-date = November 16, 2020 }} In 1973, another small portion opened just south of Mount Vernon.{{Illinois road map |year = 1973 |access-date = November 16, 2020 }} By 1975, two portions of I-64 (from IL 4 to I-57 and IL 111 to IL 159) opened.{{Illinois road map |year = 1975 |access-date = November 16, 2020 }} By 1977, the rest of the route opened. As a result of the completion, US 460 was completely removed from Illinois.{{Illinois road map |year = 1977 |access-date = November 16, 2020 }}
