Channel Tunnel Explained: Inside the $15 Billion Underwater Engineering Marvel

How do you build a $15 billion tunnel 250 feet below the sea? In this episode of Best Modern Factory, we take a deep dive into the engineering marvel known as the Channel Tunnel (or "The Chunnel").
Connecting the UK and France, this is officially the world’s longest underwater tunnel. From the massive 1,100-ton Tunnel Boring Machines (TBMs) to the precise laser guidance systems that ensured both sides met perfectly in the middle, we break down the entire 7-year construction process.
What you’ll learn in this video:
The groundbreaking technology used to dig through chalk marl.
How engineers managed the immense water pressure.
The logistics of coordinating 13,000 workers and two different nations.
The secret service tunnel that keeps the whole system running.
