History

SBI Route 172 originally ran from Libertyville to Gurnee; this became "Illinois Route 63", and then Illinois Route 21. In 1946 Illinois 172 was used on former "Illinois Route 226", which in addition to its current route ran west to Prophetstown, forming a 'T'-shaped route. The 'spur' to Prophetstown was dropped in 1974. There have been no changes since.
