Final answer:
The PWA projects provided work and improved areas with significant infrastructures such as highways, buildings, and dams. They were part of the government's effort to combat the effects of the Great Depression and were funded by the National Industrial Recovery Act.
Step-by-step explanation:
The projects undertaken by the Public Works Administration (PWA) have a common theme in that they provided work for people during the Great Depression and improved the areas in which they were conducted.
From the creation of major infrastructure like Highways, federal buildings, and military bases, to the construction of everyday facilities such as schools and hospitals, the PWA projects had a lasting impact. Examples of these projects include the Bonneville Dam, the Hoover Dam, the Golden Gate Bridge, and the Queens-Midtown Tunnel.
The PWA did not necessarily limit its activities to highly populated areas; it was also involved in developing the Tennessee Valley Authority (TVA), which focused on a whole region's development. The program worked with private contractors on public works projects funded by the National Industrial Recovery Act (NIRA) and impacted both urban and rural spaces across the country.
