Willow Springs International Raceway

Opened in November 1953, Big Willow is considered the oldest permanent road course in the United States and still uses its original layout. NASCAR's Grand National series raced there in 1956-57, and the Huth family owned and ran it from 1962. After being put up for sale in 2024, it passed to CrossHarbor Capital Partners, and the complex also includes the Streets of Willow, Horse Thief Mile, a kart track and small ovals.
