On January 1, 1969, the Iowa State Highway Commission, now known as the Iowa Department of Transportation, renumbered several state highways. The changes to the highway system fixed a number of issues: creating continuous route numbers across state lines, removing duplicate route numbers where they were unnecessary, and extending route numbers in some locations. Twenty-six sections of highway were assigned new route numbers, duplicate route numbers were removed on eleven sections, and one route number was extended to another section.[1]
