It constructed thousands of public buildings and bridges, over 500,000 miles of roads, and 600 airports. It built stadiums, swimming pools and sewage treatment plants. It employed many out-of-work white collar workers and professionals, even doctors and dentists. It hired hundreds of artists to work decorating public buildings with murals. It hired writers to produce local histories and guidebooks to the forty-eight states and to record the recollections of ordinary Americans, including hundreds of former slaves.

Explanation:

The Works Progress Administration, later Work Projects Administration (WPA), was a government agency in the United States that was started under the New Deal in 1935.

The total number of people employed in public works organized by the Public Works Administration (WPA) in the second half of the 1930s and early 1940s reached 4 million people. With family members employed in government jobs, up to 20 million Americans improved their living conditions. Over a million kilometers of roads and tens of thousands of bridges were built across the country. Almost every community in the United States has a school, bridge, or park created with the help of the Office. In the framework of the project, in particular, the President's suburban residence of Camp David (1935-1938), the Golden Gate Bridge in San Francisco (1933-1937), and the Griffith Observatory in Los Angeles (1933-1935) were built by the WPA.

During World War II, demand for labor rose again in America, so the project was discontinued in 1943.
