U.S. Route 218 marker

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.

U.S. 218 is part of the Avenue of the Saints between Floyd and Cedar Falls, and again between Cedar Rapids and a point south of Donnellson. North of Mount Pleasant, the parts of US 218 that follow the Avenue have been completely upgraded to four lanes, with either at-grade intersections or controlled access. When 218 is part of the Avenue of the Saints, it is co-signed with Iowa Highway 27.

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.
