U.S. Highway 218 (US 218) is an originalUnited States Highway that was created in 1926. Although technically a spur ofUS 18, US 218 neither begins nor ends at US 18, but overlaps US 18 for eight miles (13 km) nearCharles City, Iowa. US 218 begins atU.S. 136 in downtownKeokuk and ends 319 miles (513 km) away atInterstate 35 (I-35) andUS 14 atOwatonna, Minnesota. A large portion of US 218 in Iowa is part of theAvenue of the Saints, which connectsSt. Louis, Missouri, andSaint Paul, Minnesota.
US 218 begins in downtownKeokuk at an intersection withUS 136 andUS 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 mainlineUS 61, which bypasses the city. US 218 and US 61 head northconcurrently for a few miles before US 218 exits to the northwest; US 61 follows theMississippi River north towardsFort Madison. US 218 travels northwesterly for almost ten miles (16 km) along a two-lane road. As it approachesDonnellson, it meets up with and joinsIowa Highway 27 (Iowa 27), the Avenue of the Saints.
The two highways head north on a four-laneexpressway. In Donnellson, they meetIowa 2 at adiamond interchange. Further north, and east ofHoughton, they intersectIowa 16 at anat-grade intersection. Prior to crossing theSkunk River, the roadway angles to the northeast and afreeway bypass ofMount Pleasant begins. From the east, the highways are joined byUS 34 andIowa 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.
From Mount Pleasant it continues to theIowa City area, which it bypasses to the south and west. The US 218/IA27 concurrency intersects with I-80, and continues north withI-380 towardsCedar Rapids. There US 218 diverges from IA 27 and joins the US30/US151 bypass of south Cedar Rapids. US 151 heads south at Exit 248, and the US 30/218 concurrency continues west for 15 miles, where US 30 continues on as a 4 lane highway and US 218 exits north as a rural 2 lane highway. US 218 heads northwest throughVinton andLa Porte City before it reaches the Waterloo area.
Route 218 remains a 2 lane highway until it becomes a freeway right beforeUS 20 and once again joins I-380 for a couple miles to downtownWaterloo. When I-380 ends, US 218 continues through downtown Waterloo and then toCedar Falls, where it crosses theCedar River. It continues northwest as a 4 lane highway throughWaverly,Charles City, andOsage until the Minnesota state line.
US 218 enters the state atLyle, inMower County. It follows along the east side of theIowa, Chicago, and Eastern Railroad line as it continues northward through farm fields. Southeast ofAustin, US 218 angles northeastward to bypass the city, its former route following County Road 45 (CR 45) into town.[1]
US 218 passes by the Austin Municipal Airport just before its interchange withI-90. The highway runs concurrently with I-90 for nearly three miles (4.8 km) through northern Austin. 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 withState 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.[1]
The highway entersDodge County for less than a mile, then reachesSteele County,Blooming Prairie, and an eight-block-long concurrency withMN 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 ofBixby.
After passing through the unincorporated community ofPratt, US 218 meetsUS 14 at a folded diamond interchange. US 218 runs westward concurrently with US 14, while its historic route through downtownOwatonna continues ahead as CR 48. After an interchange with CR 45 (formerUS 65), US 14/US 218 passes by Kaplan's Woods Park and reachesI-35, where US 218 ends.
Legally, the Minnesota section of US 218 is defined as Route 40 in Minnesota Statutes § 161.114(2).[2]
In 1913, work on the road that is now US 218 was begun. At this time it was called theRed Ball Route. It was called this because the original route was marked with poles which had redballs, six inches (150 mm) indiameter, mounted on each side. In 1920, the Minnesota portion of the route was designated asConstitutional Route 40, as part of the Babcock Amendment that established the Minnesota trunk highway system.
InIowa, US 218 was extended from its previous southern terminus, at its intersection withUS 30 in Benton County, in 1934 whenUS 161 was split and renamed. The former US 161 had extended fromDubuque, throughCedar Rapids, toKeokuk. After the split, the section of former US 161 from Dubuque to Cedar Rapids extendedUS 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 ofAustin, Minnesota andOwatonna, Minnesota,[3][4] the latter following a route that would later become the US 14 bypass of that city as well.
In 1985, US 218 was bypassed around Iowa City and Coralville, joiningI-380 at the I-80 interchange. US 218 to Cedar Rapids was replaced byIowa 965.[5]
The Iowa Department of Transportation has plans to rebuild the AOTS interchange with I-80 and I-380/US 218/Iowa 27 inCoralville. 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 rebuild the interchange as aturbine interchange, which will eliminate weaving. The project is scheduled to begin in 2020.[6]
