 Five miles (8 km) east of the speedway in an exit for Iowa 224 which connects to Kellogg. After this interchange, the highway curves to the northeast and descends a hill to cross the North Skunk River. Shortly after the river, it curves back to the east and climbs up the hill. As the road straightens out, it begins a 35-mile-long (56 km) stretch of straight higwhay. Between the river and the Iowa 146 exit south of Grinnell, the farmland that surrounds the interstate undulates. Just south of Malcom, it meets US 63. Further east, at exit 201 for Iowa 21, there are competing truck stops on either side of the freeway. A hotel is located on the northern side.
