High Quality Content by WIKIPEDIA articles! New Hampshire Motor Speedway is a 1.058-mile (1.703 km) oval speedway located in Loudon, New Hampshire which has hosted NASCAR racing annually since the early 1990s, as well as open wheel racing during the 1990s. The track was originally the site of Bryar Motorsports Park before being purchased and redeveloped by Bob Bahre. The track is currently owned and operated by Speedway Motorsports.The track opened as New Hampshire International Speedway 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. Its construction was extremely unusual for a race track, in that it was designed and constructed without consulting engineers, and using just one survey to help.
