The Works Progress Administration (WPA) was a federal agency in the United States created during the Great Depression to provide jobs and economic relief to millions of unemployed Americans. It operated from 1935 to 1943, employing millions of workers to carry out public works projects such as building roads, bridges, and public buildings, as well as funding cultural programs in the arts, theater, and literacy. The WPA is credited with making significant contributions to American infrastructure and culture, while providing vital employment during a time of great economic hardship.
