[edit] History
The current version of Iowa Highway 21 is the second occurrence of the route number in the state. The first one went north from Ida Grove to the Minnesota border and was eventually replaced by U.S. Highway 59.[1]
The current Iowa Highway 21 was created in October 1934 and went between Victor and Dysart. It was extended south in 1939 to from Victor to Iowa 92, north from Dysart to U.S. 20 in Waterloo in 1969, and south again from Iowa 92 to Iowa 149 in 1980.[1]
