[1] It is four-lane road for most of its length, and six lanes through a very high-traffic corridor between Hoffman Estates and Schaumburg.

The only section that is not multilane is from just east of Waverly Drive in Elgin to just west of Barrington Road in Hoffman Estates.

The junction of Illinois 58 and Illinois Route 72 (Higgins Road) in Hoffman Estates form one of the only six-lane by six-lane sharply angled intersections in the state.

In Des Plaines, Illinois 58 and U.S. 14 (as the Northwest Highway here) use other minor feeder roads to provide access to each other.
