Riverside International Raceway (Johnsonverse)

Riverside International Raceway (sometimes known as Riverside, RIR, or Riverside Raceway) is a motorsports race track and road course established in the Edgemont area of Riverside County, California, just east of the city limits of Riverside and 50 miles east of Los Angeles, in 1957. In 1984, the raceway became part of the newly incorporated city of Moreno Valley. Riverside is noted for its hot, dusty environment and for being a somewhat complicated and dangerous track for drivers. It is also considered one of the finest tracks in the United States. The track opened on September 22, 1957. After the 1988 Budweiser 400, a shortened version of the circuit has been kept open for car clubs and special events, while the full circuit has been used for testing purposes and for other leagues.
