Travel directions
I-380 at Waterloo.
I-380 through Cedar Rapids.
Highway US 218 becomes Interstate 380 at Iowa City at the interchange with Interstate 80, the highway from Des Moines to Chicago. Just north of this, it crosses the Iowa River. Soon you reach the town of Cedar Rapids, which has a population of 124,000. Here one crosses the US 30, which is temporarily a highway. US 30 runs from Marshalltown to Clinton on the Illinois border. I-380 then runs elevated through downtown Cedar Rapids, and was one of the few dry points during the region’s major floods of 2008. One then crosses the River Cedar, passing the small business center of the city, which has some high-rise buildings. 2×3 lanes are available through the center. You then leave the city and return to the flat countryside. I-380 turns northwest here. No places of interest are encountered until US 20, and I-380 ends at US 20, which runs from Waterloo to Dubuque.

History
I-380 was built a little later than most other Interstate Highways in Iowa. Cedar Rapids is the largest city that is not on a main route of an Interstate Highway. The first section of the highway opened in 1973 between I-80 at Iowa City and East Iowa Airport. In 1976 it was extended into Cedar Rapids, and in 1979 the downtown section opened, including the bridge over the Cedar River. In 1981 and 1983 it was extended northwardly by Cedar Rapids, but most of it opened in 1985 between Cedar Rapids and Waterloo.

Interstate 480 or I -480 is an Interstate Highway in the U.S. state of Nebraska, and a minimal portion in the state of Iowa. The highway forms a semicircle around downtown Omaha, the largest city in the state. The highway is 8 kilometers long.
Travel directions
The highway begins south of downtown Omaha at Interstate 80, the highway from Lincoln to Des Moines. Interstate 80 is one of the most important transportation axes in the United States. I-480 has 2×4 lanes here as the highway heads north. At the height of the center the highway is below ground level, and there are 2×3 lanes available for traffic. The highway then curves east, while US 75 continues straight north. One then crosses the Missouri River in 2×2 lanes to the state of Iowa. Shortly thereafter, I-480 ends in Council Bluffs on Interstate 29, the Kansas City highwayto Sioux Falls.
History
The construction of the highway did not go without a fight, in the 1960s there was a lot of resistance to it. The highway was completed in 1966. There are plans to extend I-480 southwards over existing US 75 and then cross the Missouri River south of Omaha. The interchange with US 75 is also currently being modernized, which was completed in 2009.
