History

From 1918 through 1935, SBI Route 18 ran from Chicago to Princeton using what used to be part of U.S. Route 32.[3] Since then, IL 18 as well as part of US 32 were superseded by US 34.[4] In 1939, it was applied to what was then SBI Routes 89B and 89C as well as part of SBI Route 17.[5][6] The next year, the route was completed and Illinois 17 moved to a new highway south of Streator.[7][2]
