The PWA headquarters in Washington planned projects, which were built by private construction companies hiring workers on the open market. Unlike the WPA, it did not hire the unemployed directly. More than any other New Deal program, the PWA epitomized the progressive notion of "priming the pump" to encourage economic recovery. Between July 1933 and March 1939, the PWA funded and administered the construction of more than 34,000 projects including airports, large electricity-generating dams, major warships for the Navy, and bridges and 70 percent of the new schools and a third of the hospitals built in 1933–1939. Streets and highways were the most common PWA projects, as 11,428 road projects, or 33 percent of all PWA projects, accounting for over 15 percent of its total budget. School buildings, 7,488 in all, came in second at 14 percent of spending. PWA functioned chiefly by making allotments to the various federal agencies; making loans and grants to state and other public bodies; and making loans without grants (for a brief time) to the railroads. For example, it provided funds for the Indian Division of the
Civilian Conservation Corps (CCC) to build roads, bridges, and other public works on and near Indian reservations. in Montana; spillway construction. One of the largest dams in the world, it continues to generate electricity. In July 1936, its construction employed 10,500 workers. The PWA became, with its "
multiplier-effect" and a first two-year budget of $3.3 billion (compared to the entire GDP of $60 billion), the driving force of America's biggest construction effort up to that date. By June 1934, the agency had distributed its entire fund to 13,266 federal projects and 2,407 non-federal projects. For every worker on a PWA project, almost two additional workers were employed indirectly. The PWA accomplished the electrification of rural America, the building of canals, tunnels, bridges, highways, streets, sewage systems, and housing areas, as well as hospitals, schools, and universities; every year, it consumed roughly half of the concrete and a third of the steel of the entire nation. The PWA also electrified the
Pennsylvania Railroad between
New York City and
Washington, DC. At the local level, it built courthouses, schools, hospitals, and other public facilities that remain in use in the 21st century.
