South Dakota Highway 12 was a state route that ran across north central and northeast South Dakota.
[edit] History
South Dakota 12 was one of the numbers assigned to the Glacier Trail. In 1926, U.S. Highway 12 was implemented, and ran 15 or 20 miles to the south. Because the two Highway 12 routes were so close, the state highway was redesignated as South Dakota Highway 10 in 1927.
