Multilane Artery
The road is four lanes for the majority of its length, except for two small sections. The road is six lanes wide for a mile-long stretch in Algonquin (between Corporate Parkway and Harnish Drive), to accommodate traffic generated by the large outdoor malls Algonquin Commons and the Algonquin Galleria and power center Oakridge Court. The road was also widened to six lanes in small stretches in Elgin near I-90, to accommodate traffic generated by Sherman Hospital and the Elgin Auto Mall. Randall Road narrows to two lanes south of Interstate 88 in Aurora. A busy north-south artery, traffic counts average between 39,000 and 47,000 vehicles per day in the corridor from South Elgin to Lake in the Hills, between 28,000 and 39,000 vehicles per day in the Crystal Lake area and in the corridor from South Elgin to Batavia, with lighter volumes (12,000 to 17,000 vehicles per day) in the North Aurora and Aurora areas.
Some of Randall Road's more important intersections are with Illinois 31 via Rakow Road in Crystal Lake, Algonquin Road in Algonquin, Huntley Road in Carpentersville, Illinois Route 72 in West Dundee, Big Timber Road and U.S. Route 20 in Elgin, Illinois Route 64 and Illinois Route 38 in Saint Charles, Fabyan Parkway in Batavia, Orchard Road in North Aurora, and Indian Trail Drive and Galena Boulevard in Aurora. Randall Road has a complete interchange with Interstate 90 in Elgin, but does not have an interchange at Interstate 88, probably because the original East-West Tollway terminated just a few miles to the west. As a result, travelers will usually use Orchard Road to access Interstate 88.
