History
editBy 1937, US 67 was signed on part of present-day IL 203.[3] From 1938 to 1955, US 66 City was signed on this particular route as well.[4][5] By 1939, US 67 Alternate was signed after US 67 was rerouted away from East St. Louis.[6] Up until 1964, parts of IL 3, IL 162, and US 67 Alternate utilized present-day IL 203.[7] In 1964, IL 203 was signed; replacing these routes. It originally traveled to Hartford, but this was later trimmed back to I-270 as of 1989.[2][8]
