[1] On the southern edge of Kellogg, it crosses the North Skunk River and a line of the Iowa Interstate Railroad.

Iowa 224 represents the eastern boundary of Kellogg as the vast majority of the town is to the west.

North of Kellogg, the highway passes and provides access to Rock Creek State Park, which lies three miles (4.8 km) to the east.

One mile (1.6 km) from its northern end, Iowa 224 breaks from its northerly path and turns west at Jasper County Road E17 (CR E17).
