The routes under study have both regional and interstate significance. Illinois Route 47 (IL 47) is primarily a rural north–south state highway that runs from central Illinois to Wisconsin for a distance of approximately 170 miles. Within the metropolitan Chicago area, IL 47 has been designated a Strategic Regional Arterial (SRA). The SRA network is a regional arterial system designed to carry high volumes of long-distance traffic. The SRA network supplements the regional expressway system. Interstate 88 (I-88) is an interstate that runs from western Illinois to metropolitan Chicago for a distance of approximately 140 miles. This section of I-88 is under the jurisdiction of the Illinois Tollway and is designated the Ronald Reagan Memorial Tollway. Since 2010, all of I-88 has been part of the Chicago–Kansas City Expressway (CKC) and designated Illinois Route 110.
IL 47 was constructed in the early 1930’s. The existing interchange was constructed in 1975 and the freeway was designated Illinois Route 5 (IL 5) as the East-West Tollway. In 1987, IL 5 was given the designation Interstate 88 (I-88) by the American Association of State Highway and Transportation Officials (AASHTO). In 2004, this section of I-88 was designated the Ronald Reagan Memorial Tollway.
