History

Iowa Highway 175 was originally designated in 1930 as a very short spur from US 65 to Hubbard but extended west to Stratford by 1937. Iowa 175 extended west to Auburn in October 1940, replacing Iowa 91, a spur route from Dayton to US 169, Iowa 47, a spur route from US 169 to Farnhamville (which had extended west from Gowrie on December 20, 1938), Iowa 287, a spur route from Farnhamville to Iowa 17 (now Iowa 4), and Iowa 188 (which was renumbered from Iowa 151 in 1938), which went from Iowa 17 to Auburn. In January 1948, Iowa 175 extended west to US 75, replacing Iowa 35 and a duplex with Iowa 37 was created; Iowa 37 would be truncated to Iowa 175 on May 11, 1966. By 1955 Iowa 175 had extended westward to Nebraska, replacing Iowa 165. The final segment of Highway 175 was commissioned in 1969, extending the highway eastward from Hubbard to its present eastern terminus.
