History

Though Illinois 117 now connects to Illinois 17, they were originally unconnected, and each were separately planned in State Bond Issue sequence. SBI Route 117 originally ran from U.S. Route 150 in Goodfield to Illinois 116 north of Eureka. On January 8, 1993, it was extended north through Roanoke and north to Toluca to renumber IL 116A, the last surviving letter route in Illinois.
