New Hampshire International Speedway is a 1.058 mile oval track which has hosted NASCAR racing since the 1990s. It is commonly referred to by its location, Loudon. The track was opened in June 1990, after nine months of construction following the Bahre family's purchase of the Bryar Motorsports Park. The existing road circuit was redeveloped into a multi-purpose track, with NASCAR added to the popular Loudon Classic motorcycle, WKA go-kart and SCCA races on the complex. It was the largest speedway in New England, and later expansion has made it the largest sports venue of any type in the region. NASCAR made its debut at the track in July 1990, with a Busch Series race won by Tommy Ellis. For three years, the Busch Series hosted a pair of races at the track each year.

Located on approximately 1,100 acres, the multi-use complex is the largest sports facility in New England and features a 1.058-mile oval speedway, with a total capacity for 105,491 spectators, and a 1.6-mile road course.
