Illinois Route 62 (IL 62) is a 20.82-mile-long (33.51 km) east–west state highway in northeastIllinois. It runs from westernAlgonquin atIL 31 (Western Algonquin Bypass) to the intersection withIL 83 (Elmhurst Road) by industrialMount Prospect.
IL 62 is called Algonquin Road for its entire length, and it is a northern parallel toInterstate 90 (I-90). It is one of the few state roads in Illinois to be shorter than the name of the road that it marks, as Algonquin Road continues westward as McHenry CR A48 toIL 47 (about eight miles [13 km]), eastward as a local road to Oakton Street and Riverside Drive byI-294 (about five miles [8.0 km]), and northward as a local road toU.S. Route 14 (US 14, about five miles [8.0 km]) inFox River Grove. The eastward extent of Algonquin Road is mainly residential, however. It is a four lane street through downtown Algonquin and then shifts to a two lane rural road east ofIL 25. It returns to a four lane urban artery east ofIL 59.
In 2017, IL 62 had an average daily traffic (ADT) of 35,000 on the segment between in Algonquin west of IL 25; 27,000 on the segment between IL 25 and Helm Road; and 39,000 on the segment east of IL 68.[2]
SBI[citation needed] Route 62 was Algonquin toChicago along the current IL 62. It followed Oakton Street and Talcott Road (inPark Ridge) to reachIL 43. By 1979, IL 62 was dropped east of IL 83.[3] In 2014, the western terminus of IL 62 was extended west from Main Street to Western Algonquin Bypass.
The Western Algonquin Bypass opened to traffic in September 2014. The bypass has a diamond interchange with Algonquin Road. The bypass removes through north–south traffic on IL-31 from Main Street at the intersection of Main Street and Algonquin Road/IL 62 in downtown Algonquin.[4]
The Western Algonquin Bypass is not the only limited access bypass on the table anymore as of 2015.[5] A southern Algonquin bypass is also being constructed as theLongmeadow Parkway which terminates at IL 62 in Barrington Hills.
Starting in 2017, theIllinois Department of Transportation (IDOT) conducted a study of IL 62 from IL 25 to IL 68. The recommended alternative is to convert this section of IL 62 into a four-lane divided highway with a separate multi-use trail.[6] When this is completed, IL 62 will be four lanes for substantially its entire length.
