Big Diamond Speedway is a three-eighths-mile high-banked dirt oval raceway located in Pennsylvania's Coal Region.
In 1972 Fritz Roehrig completed a surface mining job in Schuylkill County, Pennsylvania, then with partner Dom Muscara built a stock car racetrack and named it after the famous vein of coal they had just mined: "Big Diamond".
[2][3] After 41 years, Rohrig sold the facility in 2012 to his son and daughter-in-law, Jake and Jasmine Smulley.
The facility hosts several touring series including the Super DIRTcar Series, USAC National Sprint Cars, URC Sprint Cars, East Coast Legend Series, Mid Atlantic Modifieds, Wingless Sportsman, and the PASS 305 Sprints.
