Between 1948 and 1979, Trenton Speedway, located in adjacent Hamilton Township, hosted world class auto racing. Drivers such as Jim Clark, A. J. Foyt, Mario Andretti, Al Unser, Bobby Unser, Richard Petty and Bobby Allison raced on the one-mile (1.6 km) asphalt oval and then re-configured -mile race track. The speedway, which closed in 1980, was part of the larger New Jersey State Fairgrounds complex, which also closed in 1983. The former site of the speedway and fairgrounds is now the Grounds for Sculpture.
