Named after one of Seattle's early mayors, the $80 million drill Big Bertha is 326 feet long, weighs 6,700 tons, and does much more than drill. John Blackstone reports on what the high-tech machinery can do, as well as its latest challenge digging in the depths of Seattle.

This comes out of our asses.. don't let them fool.. you. Soon we will have a tax raise out of nowhere.

Too bad our new giant drilling machine cant drill through mud, oh well.
Modern drones show us that we should have flying cars by now anyway.
Guess we'll have to spend the rest of your tax dollars on more FEMA camps with extra razor wire and crowd control technologies to keep all you little people under control. -
Wow imagine how much that costs to do that, imagine if that same amount of money was applied to education instead of digging a stupid fucking tunnel

The Russians have a bigger one @ 19.25 meters making the Orlovski Tunnel. They even get 3 lanes each way.

"Big Bertha" is the world's widest TBM but not the largest in terms of length. The longest TBM is used in the Gotthard Base Tunnel Project in Switzerland. It has a length of 410 meters.
