Public Works

The first electric power generated by the Theodore Roosevelt Dam for commercial use was transmitted over a high-voltage line to Phoenix, where it was employed to operate the city's new streetcar system. 

Designed to connect the Shenandoah National Park in Virginia and the Great Smokey Mountains National Park in North Carolina, the Blue Ridge Parkway was planned to provide pleasant motoring and to conserve and interpret the unique natural and cultural resources of the Southern Highlands. It was conceived also as a public works project to relieve unemployment in the Appalachian region during the Great Depression.

The terminal, designed by noted architect Joseph Finger and built by the Works Progress Administration, is a rare remaining example of classic art deco airport architecture, featuring the distinctive design elements of that age: step forms, sweeping curves, and intricate geometrical patterns and motifs. Opened on September 28, 1940, the terminal was Houston’s gateway to the world, and served the fleets of Braniff Airlines and Eastern Air Lines.

The Bonneville Dam, Columbia River Power and Navigation System consists of 55 major projects on Oregon's Columbia River and is said to be the largest hydroelectric system in the world.

The Columbia River forms part of the border between Washington and Oregon and flows inland through the only waterway that crosses the Cascade Mountains. To harness the energy of the ninth longest river in North America, engineers developed unique design and construction approaches to overcome problems caused by depth of water, current velocity, and an irregularly-shaped river bottom.
