Extreme Engineering - Season 2 (2023)

The Eastern Highland, a vast plateau 100 miles south of the Artic Circle, is the site of a bold challenge of extreme engineering. World-class tunnel diggers are carving more than 45 miles of tunnels through solid rock hundreds of feet underground.

The longest cable-stay bridge in the United States is located in Charleston, S.C.

Build the tallest skyscraper in Northern Europe? Only hope they're up to the challenge. And there's a catch: this twisted nightmare of a structure has to complete a 90-degree turn before reaching its final floor, 600 feet up.

At the world's largest open pit iron mine, a $10 million new, custom-built super shovel is commissioned to meet a sudden worldwide surge in the demand for iron. Will miners find success with the fastest, most technologically advanced excavator ever made?

America runs on oil. One-third of that oil gets pumped from wells drilled in the Gulf of Mexico. Follow the dangerous construction of the real workhorses of America's offshore drilling industry- the massive and mobile contraptions known as jack-up rigs
