History

Шаблон:Further Iowa Highway 12 was designated as a state highway in 1920. It originally went between Hamburg and Akron. It was shortened to Missouri Valley in 1924, and Sioux City in 1926. In 1931, it was extended north to Hawarden. In 1958, it was shortened to its intersection with I-29, but then in 1979, was extended east along I-29 and the newly formed Business Route 20 to end at the new U.S. 20 bypass in eastern Sioux City. In 2000, signage for this extension was removed and signage for Iowa 12 ended at I-29, though officially, Iowa 12 continues east through Sioux City.
