Greenwood Roadway was an auto and motorcycle paved racetrack located in Otter Township, Warren County, 28 miles (45 km) south of Des Moines, Iowa, on Highway 65.
Other major events included AMA National Championship motorcycle races and a round of the United States Auto Club stock car series.
Greenwood Roadway was a 3.0-mile (4.8 km) long track with varying widths from 24 to 65 feet (7.3 to 19.8 m).
However, poor spectator access and a lack of sufficient seating hindered the track's attendance.
Plagued by pavement problems and little revenue, the operators of the track were forced to close it down.
