In the U.S. state of Iowa, Interstate 35 runs north-south through the Des Moines area, parallel to US 65 and US 69. Segments of the interstate highway overlap with Interstate 80 and Iowa Highway 27, Iowa's designation for the Avenue of the Saints.

[edit] Route description

Interstate 35 enters Iowa from Missouri south of Lamoni. It goes north-northeasterly and meets Iowa Highway 2 near Decatur City. It turns north and meets U.S. Highway 34 at Osceola and Iowa Highway 92 west of Martensdale. It continues north, enters the Des Moines metropolitan area and meets the Iowa Highway 5 freeway at West Des Moines. Further on in West Des Moines, at the West Mixmaster Interchange, I-35 meets Interstate 80 and Interstate 235. I-235 serves downtown Des Moines, while I-35 and I-80 overlap and serve the western and northern Des Moines suburbs. On the Clive/Urbandale border, I-35 and I-80 meet U.S. Highway 6. Further north in Urbandale, they meet Iowa Highway 141 and turn eastward. They also meet U.S. Highway 69 north of Des Moines. Between Des Moines and Ankeny, at the East Mixmaster interchange, I-35 and I-80 separate at an interchange where they also meet I-235.

Interstate 35 then turns north to go through Ankeny. It continues north and at Ames meets U.S. Highway 30. Ames is also served by Business Loop 35. I-35 continues north and meets Iowa Highway 175 near Ellsworth and meets the U.S. Highway 20 freeway near Williams. It continues north until the Wright County border, where it turns northeast. On this northeasterly alignment, I-35 meets Iowa Highway 3.

Shortly after meeting Iowa Highway 3, Interstate 35 turns north again and meets U.S. Highway 18 and Iowa Highway 27 near Clear Lake. I-35 overlaps U.S. 18 and Iowa Highway 27 through the Clear Lake area, which is also served with Business Loop 35. U.S. 18 separates in Clear Lake and I-35 and Iowa 27, which serves as the designation in Iowa for the Avenue of the Saints, overlap for the rest of the way to the Minnesota border, meeting Iowa Highway 9 near Hanlontown.
