Illinois Route 83
Illinois Route 83 (IL 83) is a major north–south state road in northeast Illinois. It stretches from U.S. Route 30 (US 30, Lincoln Highway) by Lynwood and Dyer, Indiana, north to the Wisconsin border by Antioch at Highway 83. Route description. Illinois 83 passes through Cook County, DuPage County, and Lake County. It begins as part of Glenwood-Dyer Road in Lynwood, and then follows Torrence Avenue though Lansing, 147th Street/Sibley Blvd though Calumet City, Dolton, Harvey, Dixmoor, then north on Cicero, and then northwest on Cal Sag Road through Cook County. It then becomes  known as the Kingery Highway through DuPage County, and then follows Busse Road, Oakton Street and Elmhurst Road in northern Cook County. In Lake County it is named McHenry Road in Buffalo Grove, Ivanhoe Road north of Mundelein, Barron Blvd. in Grayslake and Milwaukee Avenue in Lake Villa. Illinois 83 ranges from a width of two thru lanes at either terminus to six lanes through DuPage County. It is the main north–south arterial route falling between Interstates 355 and 294 for the central portion of its routing. History. SBI Route 83 was modern Illinois Route 17 from New Boston  to Galva. In 1941 it was changed to the Lynwood-to-Antioch routing, replacing Illinois Route 52 and Illinois Route 54. In 1998, Illinois 83 was routed slightly north onto 127th Street, from Cal Sag Road. The renumbering was part of a major reconstruction project of the Illinois Route 50 intersection with Interstate 294 (Tri-State Tollway). As part of sign replacement accompanying the renumbering, Illinois 83 was added to the northbound Illinois 50 exit from southbound I-294, as the new northbound Illinois 50 ramp leads directly to Illinois 83 first. However, Illinois 83 overlaps Illinois 50 southbound at the  center of the interchange, so southbound Illinois 50 traffic also joins Illinois 83 at the end of the ramp. This is not reflected in the current signage on the tollway. A $13.4 million construction project was completed in northern Lake County by improving a 4-mile section of Illinois 83 from Petite Lake Road to the Wisconsin state line. Improvements included adding a center turn lane and intersection modernizations at Grass Lake Road, Illinois Route 173, and North Avenue. The project was completed in fall 2010.
