Extreme Infrastructure Megaprojects: Why Does America Build in the Worst Possible Places?

America’s biggest infrastructure projects are often built in the worst possible places: soft riverbeds, swamps, flood zones, crowded highways, and active waterways. See how engineers stabilize weak soil, build deep foundations, drive massive piles, dredge underwater channels, construct levees and flood barriers, and rebuild roads while traffic keeps moving. From Oregon and Florida to New Orleans, Seattle, and the Mississippi, this documentary explores the heavy equipment, construction machinery, and extreme engineering behind bridges, highways, pump stations, dams, and flood defenses—and how America keeps building when unstable ground, rising water, and nonstop traffic are all working against the project.
