History

Parts of what is now Iowa Highway 15 were originally primary roads designated in 1926. Primary Road 44 extended from Primary Road 10, now Iowa Highway 3 to Rolfe, while Primary Road 43 extended from Armstrong to the Minnesota state line. By 1947, Iowa Highway 44 had been created along the same route Iowa 15 now occupies. In 1969, then-Iowa Highway 44 was redesignated as Iowa Highway 15 to match Minnesota State Highway 15 at the state line.
