Interstate 88 was designated in July 1987 over Illinois 5 along the East-West Tollway. The change was made to allow 65 mile per hour speed limits on the mostly rural expressway. The 140.6 mile route in upstate Illinois connects the Quad Cities with Chicago, with I-88 east from Exit 44 and the Whiteside County line doubling as the Ronald Reagan East-West Tollway. Illinois 110, the Chicago Kansas City Expressway (CKC), was added alongside I-88 in 2010 as part of a new route. The CKC was created to provide an alternate to Interstate 55 and 70 between the two cities.
