The Oakland Speedway was the first motor racing track near Oakland, California, a one-mile, banked dirt oval track built in 1931, which operated throughout the Great Depression and postwar years. The track featured AAA National Championship races with Indy cars and drivers from 1931 until 1936, when the AAA pulled out of the West Coast. Thereafter the track still featured racing by members of the Bay Cities Racing Association, in roadsters and motorcycles, as well as Big Cars, stock cars, and midgets. It was known as the "fastest dirt track in the Nation".
