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.

Route description

Iowa Highway 9 enters from South Dakota as a continuation of South Dakota Highway 42, northwest of Larchwood in Lyon County. It runs south of Lester, at the northern edge of Rock Rapids and south of Little Rock. Crossing into Osceola County, Iowa Highway 60 crosses it just north and slightly west of Sibley. Continuing west, is runs to the north of Ocheyedan. Entering Dickinson County, the highway passes south of Silver Lake and then across the Little Sioux River, into Spirit Lake where it briefly joins U.S. Route 71. It dips southeasterly as it enters Emmet County, continuing into Estherville where it crosses Iowa Highway 4 and a tributary of the Des Moines River. Passing just south of Armstrong it has an intersection with Iowa Highway 15.

In Kossuth County, it passes through Swea City. East of Swea City, it is joined by U.S. Route 169. It passes north of Lakota, where US 169 turns north. Travelling through Buffalo Center in Winnebago County, takes a slight southwesterly dip to pass northeast of Thompson, continues east, and then south to join U.S. Route 69 at the northern edge of Forest City where it again turns east.

U.S. Route 218 and Iowa Highway 9 briefly overlap through Osage.

In Worth County, it travels past the northern edges of Fertile and Hanlontown, where it soon crosses Interstate 35. West of I-35, it passes through the south side of Manly.

In Mitchell County, it makes a straight run to and through Osage. It swings back north and resumes going west to Riceville, crossing the Wapsipinicon River in the process.

In Howard County, the highway makes a transition into the Driftless Area of Iowa, with progressively more rugged terrain evident as one travels east. West of Cresco, and south of Lime Springs, it crosses U.S. Route 63 before going through Cresco. In the process, it crosses two tributaries of the Turkey River.

The Black Hawk Bridge marks the eastern end of Iowa 9, the southern end of Iowa 26, and the western end of WIS 82.

In Winneshiek County, it runs southeasterly, straightening out to go through Decorah in the valley of the Upper Iowa River. In Decorah, it crosses U.S. Route 52. It again takes a southeasterly drift. In Allamakee County, the highway becomes crooked. Just east of the county line, Iowa Highway 51 meets its northern terminus. Running south of Waukon, then turns north through Waukon, briefly joined by Iowa Highway 76. In the northern part of Waukon, it curves north and east, into Lansing, through the valley of Clear Creek and downtown Lansing. Just before crossing the Mississippi River, it meets the southern terminus of Iowa Highway 26. It then turns onto the Black Hawk Bridge, where it joins Wisconsin Highway 82.
