How underwater tunnels are made

Mind-blowing engineering! The scale of that project is incredible.

Great Engineering! The fact is some of the longest underwater tunnels, like the Seikan Tunnel in Japan, go through earthquake-prone zones and are designed to withstand tremors!

Wao great Engineering

Very expensive. I work for the man who invented horizontal directional drilling.

Showed very well

Can’t make this shit up.

Absolutely incredible feat of engineering! I'm amazed.

spectacular. 👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼

It's like building a giant puzzle underwater! 🌊

interesting
