In the U.S. state of Iowa, Interstate 80 (I-80) runs east–west between the Omaha-Council Bluffs area and the Quad Cities area, serving Des Moines and Iowa City. It was built along the U.S. Highway 6 corridor and as a result, three sections of Interstate 80 overlap US 6 in Iowa. There are also significant overlaps with Interstate 29 in Council Bluffs and with Interstate 35 in the Des Moines area.

Route description

I-80 enters Iowa by crossing the Missouri River from Omaha, Nebraska. Immediately after descending the bridge and entering Council Bluffs, it meets I-29 at a Y interchange. The two Interstate Highways overlap each other for 3 miles (4.8 km). Through the southern part of Council Bluffs, there are two interchanges along I-29 / I-80 – South 24th Street and the South Expressway, the latter of which carries Iowa 192 into Council Bluffs. They diverge at another Y interchange and I-80 heads to the northeast.

Interstate 80 rolling through western Iowa

I-80 then goes northeast past Council Bluffs and follows an alignment which parallels the former alignment of Iowa Highway 191. Near Neola, I-80 meets Interstate 680. Interstate 80 then immediately turns east, paralleling a former alignment of Iowa Highway 83 west of Avoca and the current one east of Avoca. At Avoca, I-80 meets U.S. Highway 59. Near Atlantic, I-80 meets U.S. Highway 71 and U.S. Highway 6 and the first overlap with U.S. 6 begins. The overlap ends when I-80 meets U.S. Highway 169 at De Soto. Shortly afterwards, I-80 meets Interstate 35 and Interstate 235 at the West Mixmaster interchange in West Des Moines and turns north.

Interstate 80 and Interstate 35 go north through the western Des Moines suburbs until the interchange with Iowa Highway 141 and they turn east. They go east together and meet U.S. Highway 69 and then separate at the East Mixmaster interchange, which is also an interchange with Interstate 235. Shortly beyond, in Altoona I-80 meets U.S. Highway 65 and they overlap for a mile. When I-80 and U.S. 65 separate, U.S. 6 joins I-80 and their second overlap begins. The overlap continues through Newton. At Malcom, I-80 meets U.S. Highway 63. Near Williamsburg, I-80 meets U.S. Highway 151. I-80 continues east and meets Interstate 380, U.S. Highway 218 and Iowa Highway 27, the Avenue of the Saints, near Coralville.

Interstate 80 passes the Iowa 80 truck stop near Walcott.

After passing through the Iowa City area, Interstate 80 continues east and near Wilton, meets U.S. 6, and the third overlap begins. The overlap ends in northwestern Davenport where I-80 meets Interstate 280. I-80 continues east through the northern part of Davenport and meets U.S. Highway 61 and Interstate 74. I-80 passes through Bettendorf and LeClaire, meeting U.S. Highway 67 at LeClaire. I-80 then leaves Iowa to enter Illinois via the Fred Schwengel Memorial Bridge over the Mississippi River.

History

The first section of I-80 to open for traffic, 2+¹⁄₂ miles (4.0 km) from the I-35 / I-235 west mixmaster to the Douglas Avenue interchange in Urbandale opened on September 21, 1958. By 1960, I-80 stretched around the north side of Des Moines to the east mixmaster where I-35 splits away to the north.
