On July 1, 2003, the Iowa Department of Transportation transferred control of more than 700 miles (1,100 km) of highway to county and local governments in order to save money and to increase operational efficiency. Most of the highways turned over were short spurs connecting small, rural communities and state parks to the highway system.

In 2002, the Road Use Tax Fund Committee, a mix of city, county, and state transportation officials, met to review and recommend changes to Iowa's public road system. The report was necessitated by increasing costs to maintain the highway system and a level of funding that was not keeping up with the rising costs. The committee identified over 700 miles (1,100 km) of state highways which could be turned over to local jurisdictions. Most of the committee's recommendations were accepted and on July 1, 2003, over 600 miles (970 km) of state highways were turned over to the counties or local jurisdictions.

Iowa Highway 15 (Iowa 15) was a short state highway in Van Buren County. It ran from the Missouri state line, where it connected to Route 15 to Iowa 2 in Milton. The highway was in service between January 1, 1969, and July 1, 2003. While it was in service, there were two Iowa 15s in the state; the other was significantly longer and located in the northern part of the state thus avoiding confusion between the two routes.
