Bridgehampton Race Circuit was a race track located near Sag Harbor, New York, United States. The circuit opened in 1957, following a series of road races held from 1949 until 1953. It was one of the first permanent road racing venues in the United States, opening after Thompson Speedway, two years after Road America, the year after Watkins Glen International, and the same year as Lime Rock Park and Laguna Seca Raceway.[1] In its early years, Bridgehampton was host to major international series, including the World Sportscar Championship, Can-Am, and NASCAR Grand National. By the early 1970s, the track was used mostly for amateur events. From its opening day to the mid 90's the AMA (Championship Cup Series in the 90's) hosted events twice a month and was a favorite to many motorcycle road racers. The track closed permanently in 1998.
