Riverside Park Speedway

The Riverside Park Speedway is a quarter-mile (0.402-km) oval short track located in Agawam, Massachusetts, one mile north of the Connecticut-Massachusetts state line on Route 159. It is located on the grounds of the Six Flags New England theme park.

The track was opened in 1948 as a 1/5-mile (0.322-km) track, and was reconfigured over the years to its current distance. The track has been used several times for rock concerts, notably Radio 104.1 WMRQ's "Radio 104 Fest" and "The Big Day Off."

The track will hold the 2013 Spirit of Massachusetts 100 for the upcoming FARCE Modified Series season.
