1969 Iowa highway renumbering

July 2025 March 2015 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.https://news.google.com/newspapers?id=LWNFAAAAIBAJ&sjid=KbwMAAAAIBAJ&pg=7131%2C1694993 New Iowa Map Goes on Sale January 14, 1969 Telegraph-Herald January 9, 2011 Dubuque, Iowa New routes 1970
