Route description

Interstate 35 enters from Missouri south of Lamoni at an interchange for U.S. Route 69 (US 69). US 69 is immediately west of the interchange but does not pass beneath I-35. The interstate travels to the north-northeast for 4 miles (6.4 km) where it again meets US 69 east of Lamoni. Near Decatur City, it intersects Iowa Highway 2 (Iowa 2) at a diamond interchange. It continues north for 21 miles (34 km) towards Osceola, passing the small community of Van Wert.^[2]

At Osceola, I-35 intersects U.S. Route 34 on the western side of town. From US 34, it heads north, passing Terrible's Lakeside Casino. Northwest of Osceola is the western end of Iowa 152, which connects I-35 and US 69 at a narrow point between the two routes. From here, it travels 20 miles (32 km) through rural Clarke County and Warren County to an interchange with Iowa 92 ¹⁄₃ miles (0.54 km) east of Bevington.^[2]

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.

History

The first section of I-35, a 10-mile (16 km) long stretch from Cumming to Urbandale opened around September 21, 1958. Within five years, the interstate had grown to 55 miles (89 km), extending from U.S. Route 34 (US 34) Osceola to the eastern interchange with I-80 and I-235. The next two sections of I-35, 25 miles (40 km) from Ankeny to US 30 near Ames and 30 miles (48 km) from Ames to US 20 near Williams.^[1]

By 1972, I-35 was completed at the Missouri and Minnesota state lines. In southern Iowa, the last section, from Iowa 2 near Decatur City to the state line, was completed on December 2, 1970. In northern Iowa, the section from Iowa 9 near Hanlontown to the state line opened on December 12, 1972. The last section of I-35 to open, from US 20 to Mason City, opened on November 14, 1975.^[1]
