One of the world's largest concrete dams and largest concrete structures lies on the Columbia River in the State of Washington. Built in 1931, the Grand Coulee Dam is also one of the largest hydroelectric power plants. We'll explore this technological wonder.
The Empire State building rose to become the world's tallest man-made structure at a time when dreams were in short supply. Planned during the 1920s, construction was almost grounded by the Depression until the "Cathedral of Dreams" came to symbolize the indomitable American spirit. "Two stories a day" became the mission. Up went the rivets, the steel and the fearless men. In just two years the miracle of engineering was finished, justifying a nation's belief in itself. Here is the colorful story of this beloved building, including the innovations it inspired, and its enduring popularity today. From the first plans to the final rivet, explore the incredible story of the EMPIRE STATE BUILDING.
Part of Teddy Roosevelt’s dream of making America a global power was realized through the construction of the Panama Canal. The French began construction in 1880 but nine years and 20,000 lives later they realized their plans were flawed and abandoned the project. In 1904, construction resumed under American supervision. First, they controlled the diseases that had claimed so many construction workers’ lives. Then they developed an innovative design for a series of locks. Their dogged determination paid off when they united the oceans on January 7, 1914.
Towering over the Black Hills of South Dakota, Mount Rushmore was the vision of Gutzon Borglum, a combative and fiercely talented young sculptor. To elicit public support for his dream, Borglum whipped American patriotism into a frenzy, finally securing the financing he needed to embark on the creation of his awe-inspiring monument.
Over the course of 15 years, 350 men poured their sweat into Borglum's vision, using drills and explosives to chisel Washington, Jefferson, Lincoln and Roosevelt into the massive granite cliff. Here is the controversial history of this unorthodox masterpiece, including the remarkable design specifications, the tragedies and setbacks that marred its construction, and the awe it inspires to this day.
