The ULTIMATE look at Bertha’s breakthrough 

congratulations! been following the progress for years. hope the rest goes quickly.

Excellent. One of the best drone videos ever.

Thanks for posting. I'd never seen one of these at work before.

Awesome footage! Way to go Bertha.

Makes me think of the 3rd matrix movie when the sentinels breach into Zion

It was a long time coming and I was pessimistic like everyone else but now I think we can begin to call this a big success, looking forward to using the new highway

This machine is just incredible. Who needs science fiction?

Bless the maker and his water. Bless the coming and going of him.

Mind-blowing footage. I heard they nailed the location on the dot.

I got the chance to visit Seattle Last year. I loved everything except for the fact that there was a noisy, elevated freeway downtown right on the waterfront. It just seemed odd to me that it would be there. I didn't find out that there were plans to remove it and build a tunnel it until I got home and started reading about Seattle. The downtown Seattle area is going to be a lot nicer when it's all finally completed.

now how do we get it out

Bertha then: A big machine Bertha now: BIG TUNNEL MACHINE

Is this what they used to boar a hole through Ba Sing Se?

How many times did you need to replace the boring-bit? Also, how long did that replacement take? How long did disassembly take? I saw the video. It looked like 2 months.

_Bertha, lovely Bertha- you are a lovely machine!_ _And anyone who works with you,_ _will know just what I mean, whoa!_ _Bertha, lovely Bertha- sometimes I think you're a dream!_ _When we work out what you have to do,_ _You can always turn the goods out!_ _Always turn the goods out!_ _we can depend upon you!_

He's holding up an American flag but the machine that dug it was built by Hitachi in Japan.

Does this thing have an engine or use power from the grid? Or batteries?

Nice job...It took a lot of tenacity to get her to that point...People were trying to sabotage this project since the beginning...There are hundreds of great tunnels, and many are far more extensive than this one; but; They took a used TBM and made it work...You guys should be very proud; we tradesman can appreciate it!

What was the blockage?

Bertha Bertha what a what a lovely machine

What is the tunnel going to be used for?

It looks like the sandworm from dune 2021

É de dar medo ver uma máquina deste porte de tamanho.

As traffic is quite horrible in Seattle, I am surprised more tunnels for mass transit are not planned. Perhaps some technological advancement will solve the issue.

A Great Result,

I searched for "Bertha's Hole" and got this. Not what i was expecting.

Chews through concrete and rebar like nothing, that 10" pipe had nothing to do with the early breakdown.

That is a fine display of American engineering technology and the people with the heart and guts to do it

Is it robbins machine???

thanks to Chinese and Japanese creativity they are Above all

Shai-Hulud!

i feel like a kaiju is being birthed

BG DEAL!

Lo veo y me da como miedooooo 😅😳😱😱

aay only 3 years late

Like a video game lol

Isnt the enterdragons name Bertha.... so the dragon is a tunnel boring machine...? tbh makes sense bcoz it destroys blocks in its path lol

ok

Politics are nasty as always. Specially when you hit something that wasn't supposed to be there. I know I install outdoor plumbing for 7 years now. Horizontal drilling, diamond drill you name it. Like 15% of the time you find something thats not on schematics or is on schematics but should've been removed. Nobody wants to take responsibility.

german engeneering..

Only 2 years behind schedule and a quarter billion dollars over budget. Nice job wsdot. When I can get a job with you so I can piss away someone else's money?
