Historic US-112

Historic US-112Jump to: Historical Overview | Year-by-Year History | Additional Information

Initially conceived of as a spur routing, beginning at US-12 in Detroit and proceeding west-southwesterly across much of the Lower Peninsula before dipping into Indiana at Elkhart, where it terminated, US-112 later became a "loop" route rejoining its parent US-12 at New Buffalo. For many years, US-112 was the "other" Detroit-to-Chicago route, but when I-94 replaced the existing US-12, US-112 was decommissioned and its parent replaced it in its entirety. In the end, US-112 only existed for 36 years.
