How America Builds And Replaces Giant Pipelines While Traffic Keeps Moving. Extreme Engineering

How do engineers install giant pipelines beneath busy streets, highways, railways, and rivers without tearing up everything above? This extreme engineering documentary follows water pipeline construction from factory to finished network. See steel pipes rolled, welded, pressure-tested, lined, and coated before crews lower them into trenches or pull them through drilled crossings. Watch horizontal directional drilling, microtunneling, hydraulic pipe jacking, and heavy machinery at w
