History
Prior to its designation as an Interstate Highway, the route was known as
IL 5 and, before that, IL 190.
In 1975, IL 5 was extended westward to Rock Falls. Back then, only a small portion south of Rock Falls was free. At that point, there were two proposed freeways connecting each individual cities, FAP 402 (a proposed freeway to
Clinton, Iowa

) and FAP 403 (another proposed freeway to
East Moline). However, only FAP 403 was being built. By 1979, IL 5 finished completing the FAP 403 freeway.
The reason for I-88's original designation and continued existence as an Interstate has to do with a technicality in the old

(ISTHA) petitioned the
(AASHTO) to redesignate IL 5 as an Interstate, and, in 1987, AASHTO approved the request and assigned the I-88 numbering to the highway.
The NMSL would be completely repealed only eight years later in 1995, but the I-88 shields remain to this day, even though
Chicago–Kansas City Expressway (IL 110) markers are being posted throughout the entire length of I-88, since it is now part of the Chicago to Kansas City Expressway project, bannered with special "CKC" logos.

IL 5. In the late 1980s, it was renumbered I-88.
Officially, the tollway portion begins in
Rock Falls, starting at the interchange with US 30 at milemarker 44, although the first toll plaza does not appear until after the
IL 26 interchange in Dixon, making the section between US 30 and IL 26 technically a freeway. It continues as a tollway until its terminus in Hillside, although there is a free section between exit 76 (
IL 251) and exit 78 (
I-39). West of US 30 to I-80, I-88 is a freeway. The tollway portion is long.

There is no direct off-ramp access to
US 52,
IL 23,
IL 25, and
IL 83 (northbound). In addition, I-88 merges with IL 56 for a short distance.
Although a federal law, 23 U.S.C. § 111, prohibits the operation of commercial rest areas constructed after January 1, 1960, on Interstate Highways, the
DeKalb oasis was constructed at milepost 93 in 1975, prior to the route's designation as I-88, and remains in operation.
From 2005 lasting through 2012, ISTHA reconstructed and widened much of the original portion of I-88, between York Road and IL 56. Approximately $991.6 million (equivalent to $ in ) was budgeted for I-88 over that period. Between 2005 and 2009, I-88 was reconstructed and widened to four lanes in each direction between IL 59 and York Road, with work progressing gradually from west to east. The project included a reconstruction and reconfiguration of the Naperville Road interchange. Between IL 56 and the Aurora Toll Plaza, I-88 was reconstructed and widened to three lanes in each direction, including the reconstruction of the
IL 31 interchange and new bridges over the
Fox River.
