Route description

Prior to its designation as an Interstate Highway, the route was known as Illinois Route 5, and before that, Illinois 190.
The reason for I-88's original designation and continued existence as an Interstate has to do with a technicality in the old National Maximum Speed Law (NMSL). Originally passed in 1973, NMSL was amended in 1987 to permit 65-mph (105 km/h) speed limits on rural stretches of Interstate highways only. In spite of the fact that IL 5 was fully up to Interstate standards, it still had to carry a 55 mph (88 km/h) limit because of this wording in NMSL. The Illinois Department of Transportation (IDOT) and Illinois State Toll Highway Authority (ISTHA) petitioned the American Association of State Highway and Transportation Officials (AASHTO) to re-designate IL 5 as an Interstate, and in 1990, AASHTO approved the request and assigned the Interstate 88 numbering to the highway. NMSL would be completely repealed only five years later in 1995, but the I-88 shields remain up to this day.
In honor of the 40th U.S. president, Ronald Reagan, IDOT renamed the freeway portion "Ronald Reagan Memorial Freeway" upon his death in 2004. Reagan was a native of nearby Dixon. Similarly, ISTHA renamed the toll portion "Ronald Reagan Memorial Tollway." The tollway portion of I-88 was previously known as the "East West Tollway".
There is no direct off-ramp access to U.S. Route 52, Illinois Route 23, and Illinois Route 25. In addition, I-88 merges with Illinois Route 56 for a short distance. During the merge, Illinois 56 is the only tolled state route in Illinois.
As of 2007, I-88 has no spur routes. None are planned for the near future.
