History[]

Primary Road No. 13 was one of the original routes of the primary highway system, which was formed in 1920. Its original extent was statewide, starting at the Missouri state line south of Bloomfield and ending at the Minnesota state line north of Waukon. When the U.S. Highway System came around in 1926, Primary Road No. 13 was shortened significantly. The southernmost part of the route became US 63, between Ottumwa and Homestead, the route was replaced by Iowa 149, and from Homestead to Cedar Rapids, it was replaced by Iowa 150.^[4]

The route stayed more or less the same until it was shortened again in 1969. The northernmost section of road, from McGregor to Minnesota, was renumbered to Iowa 76 to match the numbered route it became after crossing into Minnesota. Between Froelich and McGregor, Iowa 13 overlapped US 18 and US 52.^[5][6] Since 1969, the routing of Iowa 13 has not changed.
