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. Please see the Historic US-112 page for more information on this historic U.S. Highway. |
