In 1990, Richard L. Diasio saw a need for a road course in Indiana that was devoted to club racers. He designed Putnam Park Road Course to be safe, fast, and challenging. Also, he wanted to build a circuit that could be viewed in its entirety from the pits, so that both participants and crew could be a part of the action at all times. Putnam Park was constructed in 1991 on 202 rolling acres just west of Indianapolis.
The track opened on Labor Day weekend with kart racing held by the Indianapolis Kart Club.
Other events that year included time trials by the Indianapolis Corvette Club; the Hoosier Chapter of the BMW Car Club of America held the first driving school; Track Time Performance Driving School held the first commercial driving school at Putnam Park.
