In 1939 the Owosso Speedway opened as a 1/4 (.250) mile dirt oval. The track would operate until 1944 when it closed to serve as a POW Camp for captured German soldiers from World War II. These soldiers were housed on the Speedway facilities and were allowed out into the community to do small jobs for the locals.
- The track resumed racing in 1946 with a brand-new high banked 1/2 (.500) mile asphalt oval sharing a front stretch with the 1/4 mile. In 1953 the 1/4 mile was paved, while the 1/2 mile remained a dirt track. In 1960 the 1/2 mile would go dormant, as it was closed because the track was allegedly too fast to be insured.
- The 1/2 mile would be resurrected in 1963 and the facility would continue on that way until 1972 when the big track was paved to go along with the already paved little track.
- In 1983 the track was converted over to dirt, for the first time since 1952 the two tracks were both dirt. The Speedway would close in 1988-1989 when the Simko family converted the 1/2 and 1/4 mile tracks over to the current 3/8 mile oval.
