History

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.
In Deerfield, Route 43 is designated a Blue Star Memorial Highway.
