History

US 161 was an original U.S. Highway; it and the rest of the system were designated in 1925 and were signed by the summer of 1926. US 161 replaced parts of two primary roads in eastern Iowa – U.S. Route 218, Primary Road No. 40, which was known as the Red Ball Route, from Keokuk to Cedar Rapids, and U.S. Route 151, Primary Road No. 28, parts of which were known as the Red X Route. The northernmost of US 161 were a part of a territorial and military road from Dubuque to Iowa City. This road, authorized by President Martin Van Buren in 1839, was known as Dillon's Furrow, named after the Dubuque merchant Lyman Dillon who surveyed the route and marked it with a wiktionary:furrow, furrow.

Upon designation, only a small portion of US 161 was paved, all of which was located in and around Cedar Rapids. A short section in Keokuk and the remainder of the route north of Cedar Rapids was graveled, but not paved. A $100 million bond bill ($ in dollars) passed and approved by a plebiscite in 1928 allowed paving to commence in earnest. The entire routing of US 161 was to be completed within six years. Paving work progressed faster in some counties than it did in others. By 1930, a hard-surfaced road existed from the Missouri state line to Olds in Henry County () and from Iowa City to northeast of Cascade in Dubuque County (). All of the route were paved by June 1932.

In January 1938, US 161 was removed from the U.S. Highway System. From Keokuk to Cedar Rapids, it was replaced by US 218, which had previously ended at U.S. Route 30 in Iowa, US 30 south of Vinton, Iowa, Vinton. US 218 was extended eastward along US 30 and then southward towards Keokuk. From Cedar Rapids to Key West, it was replaced by US 151, which had previously only existed in Wisconsin. US 151 was routed westward from Madison, Wisconsin, Madison along U.S. Route 18 in Wisconsin, US 18 to Dodgeville, Wisconsin, Dodgeville, then along U.S. Route 118, US 118 to Dickeyville, Wisconsin, Dickeyville, then along U.S. Route 61, US 61 into Iowa to Key West, and then along US 161 to Cedar Rapids.
