Route description

Iowa

US 218 begins in downtown Keokuk at an intersection with US 136 and US 61 Business (US 61 Bus.) at Main and 7th streets. The highway heads north along Main Street with US 61 Bus. As they exit Keokuk, the business route ends at an intersection with the mainline US 61, which bypasses the city. US 218 and US 61 head north concurrently for a few miles before US 218 exits to the northwest; US 61 follows the Mississippi River north towards Fort Madison. US 218 travels northwesterly for almost along a two-lane road. As it approaches Donnellson, it meets up with and joins Iowa Highway 27 (Iowa 27), the Avenue of the Saints. The two highways head north on a four-lane

When US 218 departs from the Interstate and turns back north, it becomes a four-lane divided highway for a short distance. After its junction with State Highway 251 (MN 251), the highway angles north-northwestward again following the IC&E rail line, this time on the west side of the tracks. The highway enters Dodge County for less than a mile, then reaches Steele County, Blooming Prairie, and an eight-block-long concurrency with MN 30. It continues north-northwesterly after leaving Blooming Prairie, traveling through predominantly agricultural scenery. It passes by Oak Glen Lake before going through the unincorporated community of Bixby. After passing through the unincorporated community of Pratt, US 218 meets US 14 at a folded diamond interchange. US 218 runs westward concurrently with US 14, while its historic route through downtown Owatonna continues ahead as CR 48.

History

In 1913, work on the road that is now US 218 was begun. At this time it was called the Red Ball Route. It was called this because the original route was marked with poles which had red

After the split, the section of former US 161 from Dubuque to Cedar Rapids extended US 151 south, and the section of US 30 from the former terminus of US 218 to its intersection with the former US 161 in Cedar Rapids, along with the section of former US 161 from Cedar Rapids to Keokuk, extended US 218 south. In 1965, US 218 was rerouted along bypasses of Austin, Minnesota and Owatonna, Minnesota, the latter following a route that would later become the US 14 bypass of that city as well.

Future

The Iowa Department of Transportation has plans to rebuild the AOTS interchange with I-80 and I-380/US 218/Iowa 27 in Coralville. As the Eastern Iowa region has grown, traffic has increased, and the current arrangement of the interchange with its cloverleaf ramps has been deemed unsafe.
