Illinois Route 65

For the latest routing, IL 65 began at US 30 Bus. in Aurora. It then traveled due eastward via present-day New York Street and Aurora Avenue. During this travel, IL 65 intersected IL 59 and US 34 west of Naperville. As it reached downtown Naperville, it then traveled due north via Washington Street until it ended at US 34.[3][4][5]

In 1932, IL 65 was formed. It initially traveled from US 30 (initially concurrent with IL 22) to US 32 (initially concurrent with IL 18; later US 34).[1] By 1934, it was extended from both ends; west from US 30 to Oswego and east from US 32 west of Naperville to US 32 north of Naperville. This routing made it a bypass of Aurora.[6] As of 1935, part of US 32 from Sheffield to Chicago became part of US 34.[7] In 1936, part of US 34 in Naperville switched place with part of IL 65 that bypassed Naperville.[8] By 1939, another part of the US 34 designation switched place with another part of the IL 65 designation west of Naperville. However, IL 65 ended in downtown Aurora instead.[9] In 1954, the routing became truncated as part of it in Aurora became a one-way road for US 30 (later US 30 City in 1959 and then later US 30 Bus. after 1960).[10][11][12] It eventually became decommissioned as of 1971.[2]

This junction list is based on the latest routing of IL 65 before its decommissioning.
