Originally, Iowa Highway 281 was a spur route from U.S. Highway 20 to Dunkerton. In 1957, when US 20 was rerouted to the south, Iowa 281 was extended along the former alignment of US 20 to US 63 in Waterloo. In 1980, it was extended along County Road V3C in Black Hawk and Buchanan Counties and took over the routing of Iowa Highway 190, which was a spur route connecting Fairbank to Iowa Highway 150 south of Oelwein. On the 1986 Iowa DOT map, Iowa 281 was routed south of D20 along V51 to the new US-20 freeway, but by 1986, Iowa 281 was again routed west of V51 along D20 to the eastern city limit of Waterloo.
