I-80 begins at the bridge over the Missouri River in Council Bluffs, which also forms the border with the state of Nebraska. Interstate 80 in Nebraska comes from the large city of Omaha and is double-numbered directly in Iowa with Interstate 29 along the south side of Council Bluffs. This part has large flyovers and a parallel structure up to 12 lanes wide. After the eastern interchange with I-29, I-80 veers northeast and travels 2×2 lanes in this direction for 35 miles to Minden, where Interstate 880 joins from Omaha and I-80 curves east.
The freeway then heads east across the prairies of western Iowa. The highway is characterized by long straight stretches through montoon agricultural area with few differences in height and little afforestation. There are only a few small villages on the 150-kilometer route to the capital Des Moines. A number of US Highways running north-south are crossed on this route, such as US 59 at Avoca, US 71 at Atlantic and US 169 at De Soto. Between Atlantic and De Soto, US 6 also coincides with I-80. The highway has 2×2 lanes to the edge of the Des Moines metropolitan area.
In west Des Moines, I-80 has 2×3 lanes and then bypasses west and north Des Moines, consisting of a 23-mile double-numbered interchange with Interstate 35. The highway has 2×3 lanes through the entire passage of Des Moines and bypasses downtown for some distance. Interstate 235 opens up downtown and ends at I-35/I-80 at both ends. After the split between I-35 and I-80, the highway will have 2×3 lanes for some time until the suburb of Altoona. Here is also an interchange with US 65.
East of Des Moines, I-80 crosses the monotonous prairies again. The highway has 2×2 lanes and on the 250-kilometer stretch to the Quad Cities only opens up one other larger city, Iowa City, which also has a junction with Interstate 380. The passage through Iowa City is equipped with 2×3 lanes. On the route through eastern Iowa, I-80 again crosses several US Highways, such as US 63 at Malcom, US 151 at Williamsburg and US 218 at Iowa City. I-80 is characterized by a large volume of freight traffic. Famous is the Iowa 80 Truck Stop at Walcott, the largest truck stop in the world, just west of the Quad Cities region.
The Quad Cities are four cities on the Mississippi River, two in Iowa and two in Illinois. I-80 runs along the north and east sides of Davenport and Bettendorf. Interstate 280 runs along the west and south sides of Moline and Rock Island, creating a complete beltway around the Quad Cities in the states of Iowa and Illinois. I-80 remains outside the built-up area of the Quad Cities and has 2×2 lanes throughout. At Davenport are interchanges with US 61 and Interstate 74. At Le Claire, the Fred Schwengel Memorial Bridge follows the Mississippi River to Illinois, then Interstate 80 in Illinois continues toward Chicago.

Like most Interstates, I-80 was built primarily in the early 1960s. There were already plans for the Interstate Highway plan. In 1954 a plan was presented for a toll highway that roughly follows the current route. Due to the passing of the so-called “Interstate Highway Act”, the toll road was never built, but the route was developed as the toll-free Interstate 80. The first section opened at Des Moines in 1958. This is the current I-80/I-35 double numbering around the city. In the 1960s, substantial construction was continued, and by the mid-1960s, the largest part was opened to traffic. The last section was built in 1972, this was the bridge over the Missouri River at Omaha and Council Bluffs.

Widening in Des Moines
Before 1990, the north-south section that coincides with I-35 was widened to 2×3 lanes, a 6-kilometer-long stretch between I-235 and State Route 141. Also, before 1990, a 6-kilometer-long section east of Des Moines to Altoona widened to 2×3 lanes. In the 1990s, the east-west section between State Route 141 and State Route 415 was widened to 2×3 lanes over a distance of 13 kilometers, followed by the remainder to the eastern interchange with I-35 around 2001. Between 2006 and 2010, reconstructed the eastern interchange with I-35, with the connection I-235 to I-35 becoming a through route. The left-wing inserters on I-35/I-235 were gone, but the left-wing inserters on I-80 hadn’t yet.
Widening through Iowa City

The passage of I-80 through Iowa City has been widened to 2×3 lanes, in phases from west to east. In 2004, the first section immediately east of the I-380 interchange was completed. The bridge over the Iowa River was replaced before 2004, but was not upgraded to 2×3 lanes until later, in conjunction with widening to the east side of Iowa City in 2010.
Reconstruction in Council Bluffs
Interstate 80 has been reconstructed in phases by Council Bluffs. I-80 has been widened to 2×3 through traffic, plus parallel lanes for local traffic and to and from I-29. In addition, the traffic flows on the double numbering with the I-29 are untangled. A cross section of 4×3 lanes on the I-29/80 double numbering has been realized. The nodes have also been reconstructed. The entire project cost $2 billion. The project was completed in phases, with the new bridge over the Missouri River completed in 2010, but the project will run through August 2021. On October 10, 2014, the redesigned western interchange between I-29 and I-80 opened. On October 19, 2017, the redesigned eastern interchange between I-29 and I-80 opened.
