U.S. Highway 218 is an original United States Highway, created in 1926. Although technically a spur of U.S. Route 18, US 218 neither begins nor ends at US 18, but overlaps US 18 for 8 miles (13 km) near Charles City, Iowa. US 218 begins at U.S. Route 136 in downtown Keokuk and ends 319 miles (513 km) away at Interstate 35 and U.S. Route 14 at Owatonna, Minnesota. A large portion of US 218 in Iowa is part of the Avenue of the Saints, which connects St. Louis, Missouri, and Saint Paul, Minnesota.

Route descriptionEdit


US 218 begins in downtown Keokuk at an intersection with US 136 and US 61 Business at Main and 7th Streets. The highway heads north along Main Street with US 61 Business. 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 northwest for almost ten miles (16 km) 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 Highway.

The two highways head north on a four-lane expressway. In Donnellson, they meet Iowa 2 at a diamond interchange. Further north, and east of Houghton, they intersect Iowa 16 at an at-grade intersection. Prior to crossing the Skunk River, the roadway angles to the northeast and a freeway bypass of Mount Pleasant begins. From the east, the highways are joined by US 34 and Iowa 163. The four highways loop around the city's eastern side and begin traversing the northern side when US 34 and Iowa 163 split away to continue bypassing Mount Pleasant; US 218 and Iowa 27 continue north.


U.S. 218 enters the state at Lyle, in Mower County. It follows along the east side of the Iowa, Chicago, and Eastern Railroad line as it continues northward through farm fields. Southeast of Austin, U.S. 218 angles northeastward to bypass the city, its former route following County Road 45 into town.[2]

U.S. 218 passes by the Austin Municipal Airport just before its interchange with Interstate 90. The highway runs concurrent with I-90 for nearly three miles through northern Austin. When U.S. 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, the highway angles north-northwestward again following the IC&E rail line, this time on the west side of the tracks.[2]

The highway enters Dodge County for less than a mile, then reaches Steele County, Blooming Prairie, and an 8-block-long concurrency with State Highway 30. It continues north-northwest 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, U.S. 218 meets U.S. 14 at a folded diamond interchange. 218 runs westward concurrent with 14, while its historic route through downtown Owatonna continues ahead as County Road 48. After an interchange with County Road 45 (former U.S. 65), 218 and 14 pass by Kaplan's Woods Park and reach Interstate 35, where U.S. 218 ends.

Legally, the Minnesota section of U.S. 218 is defined as Route 40 in Minnesota Statutes § 161.114(2).[3]


In 1913, work on the road that is now U.S. 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 balls, six inches (150 mm) in diameter, mounted on each side. In 1920, the Minnesota portion of the route was designated as Constitutional Route 40, as part of the Babcock Amendment that established the Minnesota trunk highway system.

In Iowa, U.S. 218 was extended from its previous southern terminus, at its intersection with U.S. 30 in Benton County, in 1934 when U.S. Highway 161 was split and renamed. The former U.S. 161 had extended from Dubuque, through Cedar Rapids, to Keokuk. After the split, the section of former U.S. 161 from Dubuque to Cedar Rapids extended U.S. 151 south, and the section of U.S. 30 from the former terminus of U.S. 218 to its intersection with the former U.S. 161 in Cedar Rapids, along with the section of former U.S. 161 from Cedar Rapids to Keokuk, extended U.S. 218 south.

In 1965, U.S. 218 was rerouted along bypasses of Austin, Minnesota and Owatonna, Minnesota,[4][5] the latter following a route that would later become the U.S. 14 bypass of that city as well.

Highway 218 was featured in the Bellamy Brothers 1976 song "Highway 2-18 (Hang On To Your Dreams)". It was track A5 on their first album, Bellamy Brothers – Featuring "Let Your Love Flow".


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. The Iowa DOT proposes to rebuilt the interchange as a turbine interchange, which will eliminate weaving. The project is scheduled to begin in 2020.[6]

The routing was created as a result of construction of the Avenue of the Saints corridor through Iowa. The new Avenue of the Saints corridor took US 218 / IA 27 and US 34 around the eastern and northern edges of Mount Pleasant. The Iowa 438 section of US 218 Business serves as a connector from southbound US 218 / Iowa 27 to westbound US 34.
