How the U.S. Built a Massive Border Wall Where It Seemed Impossible #longvideo #BorderWall #USA

DESCRIPTION How do you build a massive border wall across some of the most difficult terrain in America? Steep mountains, extreme desert heat, unstable soil, flooding, remote locations—and thousands of separate construction operations. This documentary takes you behind the steel to show the engineering, foundations, roads, drainage, lighting, cameras, sensors, communications infrastructure, heavy machinery, and the workers who bring the entire system together. What looks like a simple wall from a distance is actually a much larger construction system. Watch until the end to see how the wall becomes something far more complex than steel alone. What do you think is the most challenging part of building infrastructure like this?
