## History

State Highway 16 was designated in 1980. The route was originally part of old U.S. Highway 16 from 1926 to 1980.
U.S. 16 was mostly replaced by Interstate Highway 90 within Minnesota.
State Highway 16 from Dexter to La Crescent is the only remaining section of this former U.S. route that exists as a trunk highway separate from Interstate 90.
After crossing the Mississippi River Bridge and the Wisconsin state line, old U.S. 16 continues on as Wisconsin Highway 16.
The only section of U.S. Highway 16 that remains in the present day is the east–west route between Rapid City, South Dakota and Yellowstone National Park in Wyoming.
