Riverside International Raceway

Riverside International Raceway (RIR), formerly known as the Riverside International Motor Raceway, was an auto racing complex in Moreno Valley, California, within Riverside County. The complex featured multiple layouts, including various road course layouts, oval layouts, and a dragstrip. From its opening in 1957 until its closure in 1989, the facility hosted numerous major racing events, including Formula One, NASCAR, and IMSA GT Championship events. The West Coast Automotive Testing Corporation, led by Rudy Cleye and John Campbell Edgar, built and completed the raceway in 1957. The facility was sold in 1962 to a group led by Edwin Pauley, Fred Levy, and Bob Hope. Under the leadership of longtime track president Les Richter, the track entered financial stability and underwent renovations. The track ran its last major events in 1988; demolition started in June of that year. After some local events on a shortened version of the track, the facility ran its final events in 1989.
