The ULTIMATE look at Bertha’s breakthrough

- On April 4, 2017, one of the world’s largest tunneling machines chewed through more than 1,000 tons of concrete and fiberglass to end a 1.7 mile journey underneath downtown Seattle. With a drone’s eye view, this video shows the raw power of Bertha’s breakthrough - start to finish.
congratulations! been following the progress for years. hope the rest goes quickly.
Is this what they used to boar a hole through Ba Sing Se?
Bless the maker and his water. Bless the coming and going of him.
Excellent. One of the best drone videos ever.
Thanks for posting. I'd never seen one of these at work before.
Mind-blowing footage. I heard they nailed the location on the dot.
Bertha then: A big machine
Bertha now: BIG TUNNEL MACHINE
Awesome footage! Way to go Bertha.
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
Makes me think of the 3rd matrix movie when the sentinels breach into Zion
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.
This machine is just incredible. Who needs science fiction?
It looks like the sandworm from dune 2021
now how do we get it out
easy.
The machine will be cut into pieces and hauled away over the next several months. Some pieces may be reused on other projects while others will be recycled.
In other words, made into razor blades and Canon cameras ...
At least they aren't wasting her. The Chunnel TBM's bored their own graves and were covered up.
might i suggest putting an express tunnel through Snoqualmie?
_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.
I searched for "Bertha's Hole" and got this. Not what i was expecting.
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.
Crews stopped periodically to replace teeth on the cutterhead. There were more than 700 cutting tools on the tunneling machine's cutterhead. Tunneling machine disassembly lasted for about four months.
Does this thing have an engine or use power from the grid? Or batteries?
It used electricity with a specialized substation.
That is a fine display of American engineering technology and the people with the heart and guts to do it
American has nothing to do with the machine.. it was purely made by japanese.

Really? How would you objectively test that idea.
Seems to me that it would be similar to saying that Americans had nothing to do with the iPhone. It is *purely made by* the East and Southeast Asians.
@@samdg1234 hitachi is japanese
Bertha Bertha what a what a lovely machine
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!
A "Used TBM"? Bertha (the TBM's name) was manufactured by the Hitachi Zosen Sakai works in Osaka Japan. It was specifically designed AND built solely for the SR 99 tunnel replacement and was a BRAND NEW TBM, NOT USED!!!
Chews through concrete and rebar like nothing, that 10" pipe had nothing to do with the early breakdown.
What was the blockage?
É de dar medo ver uma máquina deste porte de tamanho.
Is it robbins machine???
thanks to Chinese and Japanese creativity they are Above all
*"creativity they are Above all"*
Pretty hard to test that thesis.
I disagree.
Hitachi is Japanese
@@HashBrownDoyler but you were too lazy to expand your argument beyond "I disagree"
@@leob4403 Your comment is too long, I'm not reading it. And there is literally nothing you can do to convince me to.
A Great Result,
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.
What is the tunnel going to be used for?
cars
It's replacing the existing Alaskan Way Viaduct running near the waterfront through downtown Seattle.
You're kidding, right????
Isnt the enterdragons name Bertha.... so the dragon is a tunnel boring machine...?
tbh makes sense bcoz it destroys blocks in its path lol
BG DEAL!
i feel like a kaiju is being birthed
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.
Shai-Hulud!
aay only 3 years late
Lo veo y me da como miedooooo 😅😳😱😱
Like a video game lol
ok
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?
Well, the viaduct wasn't suitable anymore, so they had to do something.
german engeneering..
This boring machine is made in Japan.
Lmao. Its from japan! 🤣
