Los Angeles Speedway opened in 1957, on the site of a former city dump. It was built less than from the former site of Carrell Speedway, which had been closed in late 1954 to make way for the Artesia Freeway. The track was renamed to New Ascot Stadium in October 1958 to as part of a management change. The track assumed the name it held until its closure, Ascot Park in 1961. J. C. Agajanian promoted major races at the venue, and later leased the track from 1976 until his death in 1984, when his family continued operating the venue. His radio advertisements ended with the phrase "Come to Ascot, where the 110, the 405 and the 91 freeways collide!". With seating for only 7,500, Ascot Park was smaller than the other tracks of the area including the Ontario Motor Speedway, and the Riverside International Raceway. However, the park was equally well-known, due to its being surrounded by freeways for easy access, its regularly scheduled races, and its heavy radio advertising. The half-mile course featured tight semi-banked turns, long straight-ways, and a tacky surface that was conducive to dramatic sprint car racing. Other motorsport events, such as Figure 8 racing and motorcycle flat track, TT racing and motocross, were also held at Ascot. The dirt racetrack hosted races in the United States Auto Club sprint car championship, the AMA Grand National Championship motorcycle series. Ascot was also the site of the annual USAC Turkey Night Grand Prixmidget race on Thanksgiving. Though he began doing stunt jumps in 1966 at small venues such as fairs and carnivals, Evel Knievel gained international attention with his first televised jump on ABC’s Wide World of Sports at Ascot Park Raceway on March 25, 1967, successfully clearing 15 cars. The racetrack was also used in movies and TV shows like the original Gone in 60 Seconds, A Very Brady Christmas, T J Hooker and CHiPs. The 50th annual Turkey Night Grand Prix for USAC midget cars became the last of more than 5,000 main events held since the track opened. Ascot Park was closed in November 1990. It remained unused after a failed development project occupied the former site for a number of years. The track site was later replaced by Insurance Auto Auctions building and storage yard. ESPN was hosting live races of Thursday Night Thunder sprint car racing from 1988 to the track's closing in 1990 and later went over to Indianapolis Raceway Park and the show was later moved to Saturday night, some of the most famous driver to race at Ascot was Jeff Gordon, Sleepy Tripp, among others.
