| Location | Big Foot Prairie–Crystal Lake, Illinois |
| Existed | 1928–1929[3] |
Temporary U.S. Route 12 (Temp. US 12) was a temporary route of US 12. It was formed in 1928 because a stretch of road between the Wisconsin state line at Richmond and Crystal Lake, Illinois, was incomplete. It ran from Big Foot Prairie to Crystal Lake which roughly followed present-day US 14. It was removed in 1929 after US 12 followed the completed roadway north of Crystal Lake.[4]
Des Plaines–Chicago business loop

|---|---|
| Location | Des Plaines–Chicago, Illinois |
| Existed | 1960[5]–1968[6][7] |
 City U.S. Route 12 | |
|---|---|
| Location | Des Plaines–Chicago, Illinois |
| Existed | 1938[8]–1960[5] |
City U.S. Route 12 (City US 12; signed as U.S. Route 12 Business [US 12 Bus.] after 1960) was a business route of US 12. In 1938, almost the entire section of US 12 in Illinois was rerouted. While US 12 moved north along then-Illinois Route 60 from Richmond to Des Plaines, US 12 was rerouted to bypass the Chicago Loop via US 45 and 95th Street. This diversion subsequently redesignated the former route east of Des Plaines to City US 12, albeit along a slightly different path. Before 1938, US 12 traveled along Northwest Highway, Foster Avenue, Lake Shore Drive, Michigan Avenue, and Leif Erikson (now Lake Shore) Drive. City US 12 on the South Side instead traveled along South Parkway (now Martin Luther King Drive), Midway Plaisance, and Stony Island Avenue before ending at US 12/US 20 (95th Street).[8][9][10] In 1941, City US 12 was rerouted to avoid Washington Park, traveling along Oakwood, Drexel, and Hyde Park boulevards.[11] In 1960, City US 12 was renamed to US 12 Bus.[5] In 1963, US 12 Bus. was rerouted onto the Chicago Skyway from Stony Island Avenue to US 12/US 20/US 41 (Indianapolis Boulevard).[12] In 1968, US 12 Bus. was decommissioned altogether.[6]

|---|---|
| Location | Chicago, Illinois–Hammond, Indiana |
Michigan
editMichigan has had several special routes related to both routings of US 12 in the state. Before 1962, US 12 followed what is now the I-94 corridor, and there was an alternate route in the Kalamazoo area (1931–1954) as well as business routes in Kalamazoo, Battle Creek, Marshall, Albion, and Jackson. After the 1962 realignment of US 12, these business routes were redesignated as business loops of I-94. Two business routes for US 112 in Niles and Ypsilanti were renumbered in 1962 when US 12 replaced US 112.
