Illinois Route 43 (IL 43) is a 60.30-mile-long (97.04 km) major north–south state road in the U.S. state of Illinois. It runs from U.S. Route 30 (US 30) in Frankfort north to the large intersection of IL 120 (Belvidere Road) and US 41 (Skokie Highway) in Waukegan.
Illinois 43 is called Waukegan Road for the first 20 miles (32 km) until its intersection with Oakton Street in Niles; it then follows that road west one block until it turns back south and remains Harlem Avenue for the duration. When Illinois Route 50 begins in Skokie and Illinois Route 171 begins in Chicago, It parallels those routes for much of the rest of its length. It enters, exits, and runs parallel to Chicago limits several times, passing through or parallel to Edison Park, Norwood Park, Dunning, Montclare, and Austin on the Northwest Side then Garfield Ridge and Clearing on the Southwest Side. Listed as 7200 West in the Chicago address system, it is one of seven state roads that travel through the city of Chicago.
Illinois 43 was originally part of what is now US 136 and IL 10 from Havana to Mason City. By 1935, Illinois 43 was moved to what is now Illinois Route 4 from Olive Township to Oraville. By 1964, Illinois 4 acquired all of Illinois 43. In 1967, Illinois Route 42A, which originally followed Waukegan Road and Harlem Avenue, was decommissioned and was replaced by Illinois 43.
