The Milwaukee Mile is a oval race track in the central United States, located on the grounds of the Wisconsin State Fair Park in West Allis, Wisconsin, a suburb west of Milwaukee. Its grandstand and bleachers seats approximately 37,000 spectators. Paved in 1954, it was originally a dirt track. In addition to the oval, there is a road circuit located on the infield. As the oldest operating motor speedway in the world, the Milwaukee Mile has hosted at least one auto race every year from 1903 to 2015 (except during U.S. involvement in World War II). The track has held events sanctioned by major bodies, such as the AAA, USAC, NASCAR, CART/Champ Car World Series, and the IndyCar Series. There have also been many races in regional series such as ARTGO. Famous racers who have competed at the track include: Barney Oldfield, Ralph DePalma, Walt Faulkner, Parnelli Jones, A. J. Foyt, Al Unser, Bobby Unser, Mario Andretti, Bobby Rahal, Jim Clark, Darrell Waltrip, Alan Kulwicki, Emerson Fittipaldi, Bobby Allison, Davey Allison, Nigel Mansell, Rick Mears, Michael Andretti, Alex Zanardi, Harry Gant, Rusty Wallace, Walker Evans, Dario Franchitti and Bernie Eccelstone as well as current racing stars Danica Patrick, Dale Earnhardt Jr., Jeff Gordon, Tony Kanaan, Scott Dixon, Hélio Castroneves, A.
