The original SD 32 was established in the late 1940s, from SD 45 near Gann Valley to US 81 east of Oldham. By 1954, the section from SD 45 to SD 25 was cancelled, shortening the west end to SD 25. Between 1965 and 1970, SD 32 was cancelled, and the current SD 32 was established. The current SD 32 has remained unchanged since.

The entire route is in Moody County.
