The WPA created by President Roosevelt in 1935, as a program that intended to decrease unemployment and contribute to overcome the hard times during the Great Depression, achieved to employ millions of people to carry out public works projects, such as school and hospitals buildings, bridges, airfields, reparation of roads, storm drains, sanitary sewer lines, etc.
