Speedway Field was the original name for the airfield that was to evolve into Minneapolis-St. Paul International Airport, the twelfth busiest airport in the United States; it was also the largest hub for Northwest Airlines and the third largest hub for Delta Air Lines, Northwest's successor.
Speedway Field has its beginning on December 11, 1919, when the Adjutant General recommended to civic groups of Minneapolis and Saint Paul in the U.S. state of Minnesota that the site of the former bankrupted Twin City Motor Speedway[1] be acquired for a new airfield.
The 160 acres (0.65 km2) of land inside the concrete race track oval was first used as an airfield in 1920. It was known as "Speedway Field" and also "Snelling Field" before being dedicated Wold-Chamberlain Field after two World War I pilots, Ernest Groves Wold and Cyrus Foss Chamberlain on July 10, 1923.
