Iowa Highway 9 is the most northern of Iowa's east–west highways, traversing the entire northern tier of counties. It runs from the eastern terminus of South Dakota Highway 42 at the South Dakota border east of Sioux Falls, South Dakota near Benclare, to the Wisconsin border at Lansing where it continues as Wisconsin Highway 82. It is largely rural in character, bypassing any large city. Making a few dips north and south, the highway largely follows a very straight east–west alignment.
