IL 62 is called Algonquin Road for its entire length, and it is a northern parallel to Interstate 90 (I-90).

[2] SBI[citation needed] Route 62 was Algonquin to Chicago along the current IL 62.

It followed Oakton Street and Talcott Road (in Park Ridge) to reach IL 43.

[5] A southern Algonquin bypass is also being constructed as the Longmeadow Parkway which terminates at IL 62 in Barrington Hills.

The recommended alternative is to convert this section of IL 62 into a four-lane divided highway with a separate multi-use trail.
