Redevelopment began not long after World War II. A bitumen motor racing circuit was built around the outside of the proposed horse track (which was not completed until 1965) and was first opened in 1962 and held the race which became the Sandown 500 for the first time in 1964.Motor racingWhen Sandown first opened in 1962 it held the Sandown International Cup, which featured world-famous drivers such as Stirling Moss and Bruce McLaren.
