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.
