The world's widest tunnel boring machine arrived in Seattle in pieces Tuesday aboard a ship from Japan. It will be reassembled in a pit to begin the year-long dig to create a two-mile tunnel under downtown Seattle.

The new tunnel section of Highway 99 replacing the Alaskan Way Viaduct will have a diameter of nearly 58 feet.
The Alaskan Way Viaduct has a high risk for collapse in a major earthquake and must be replaced.
Tunneling will open up a major waterfront piece of land for new parks and development.
Well it certainly won’t be boring.
Look out, masseuses. Algore is back in the Great Northwest.
Wonder why they didn’t just use a couple of those ginormous, earth-burrowing worm creatures from that movie ‘Tremors’.
Kevin Bacon, Fred Ward and Rebate McEntyre practically had them on leashes. It’s because they don’t really exist, isn’t it?
*yawn* Very boring. Even more so than the Boring Lava Field near Portland, OR.
Wake me when these things actually save money over traditional tunneling methods (mysteriously, they cost way, way more).
(Darn you auto correct. But it’s a made-up name anyway ‘cause she really doesn’t exist.)
“Tunneling will open up a major waterfront piece of land for new parks and development.”
A tunnel to nowhere?
It may be the world’s largest boring machine, but it wouldn’t make a miniscule peephole in our national debt, or, for that matter, in President Hussein’s indifference to the most basic principles of ethics and morality.
Some of the most difficult and rapid-changing geology around, under the water table, going under hundreds of Downtown Seattle buildings, and IIRC it is 10-feet larger in diameter than any other tunneling machine use in the USA. Anything but boring.
And a tunnel is completely safe in an earthquake?
Now, when the predicted 9.0 quake happens, the tunnel will just collapse burring any unsightly problems. Nothing to see there.
Only on the Farside, in lefty King County - its power over the rest of the State gone to its collective head - would actually pursue this 30 year old ‘pipe’ dream.
Now, Seattle is truly home to the world’s most boring folks. All home built. Oregon is second, bar none. All the rest are third placed by tie dye faux. Good effort Austin, Texas.
Surprised it’s not on its way to Mexico.

From Madonna’s “Marital Aide” collection...
No, it's because the graboids can only burrow thru dirt and sand, not rocks........Sheesh, everybody knows that.
What is that? The "Swiss Army Knife" approach to earth moving?
LOL! It does look like one doesn't it?
what kind of insanity digs a huge tunnel under a city deliberately??????????????
It’s not really an earth mover...bucket-wheel excavator for coal strip mining.
Agree - tunnels are not earthquake proof.
However, the Viaduct is 60 years old, double decked, and threatens to pancake everything on the first tier and at street level, like those horrible photos from Oakland and Japan from about 20 years ago.
Above ground construction is much cheaper, but the Viaduct and I-5 are downtown Seattle eyesores and severe noise polluters.
Please don’t ban me from Free Republic, but I actually voted for the much more expensive tunnel.
I was talking with a tunnel expert just the other day. He said that tunnels hold up very well under earthquakes. He was at one for repairs after a fault ruptured right through the tunnel. Offset the tunnel by 3 or 4 feet, but the damage was confined to just the area (+/- 20’) where the fault sliced through it! That surprised me.
