The World's Longest Tunnel

fusconed writes "Bloomberg reports that the Russian government is proposing to build an underground tunnel between Russia and Alaska for transporting goods, electricity and natural resources. The tunnel would be twice as long as that between the UK and France. The $10 — $12b cost is not something to be overlooked, but Russia claims the benefits would pay it off in 20 years. It would take 10 to 15 years to build, but being an Alaskan, it sounds good to me!"

Cheaper Chunnel?

[ObligatoryUserName]

According to Wikipedia, in 1990, when the Channel Tunnel was completed its cost was estimated as 10 billion GBP.

I'm no expert on inflation and exchange rates, but by estimating this tunnel at $10-$12 billion aren't they saying that a tunnel that is twice as long as the Channel Tunnel will actually cost less to build? Is there any reason to believe this will actually be so?

Look at a map for your answer.

To answer you question, all that you need to do is to look at a map of the Pacific Ring of Fire.

Here's one, in case you had trouble finding one for yourself: http://upload.wikimedia.org/wikipedia/commons/0/09 /Pacific_Ring_of_Fire.png

The Bering Strait is clearly well north of the Ring of Fire faultlines. Thus the tectonic impact will be minimal.

Furthermore, you don't throw together a $12 billion proposal and not take into account such things. Anything you can think of regarding this project has likely been thought of already by the planners. If crustal movement was to have a serious impact, we would not be hearing about this proposal, because it would have been scrapped long ago.

Actually, there is are earthquakes in Alaska. In fact, three of the the top 10 most powerful quakes in the world were located in Alaska. Just take a look here: http://earthquake.usgs.gov/regional/world/10_large st_world.php

Not truck traffic, but rail traffic, sure...

Will that enable truck traffic all the way to say, LA?

I don't think that you'd really want to bother with a road in the tunnel. Like the Chunnel, you'd probably use trains. They're more efficient, and you don't have to worry about exhaust gases building up in the tunnel (they're electric), plus they just make a lot more sense for moving bulk goods over long distances.

The Russians already have a well-developed rail infrastructure -- that's if they haven't torn it up for scrap metal lately -- and the Trans-Siberia Railway is all double-track and electrified (at no small expense, but hey, when you have a lot of peasants or comrades to employ, who cares?), so it would be dumb to transfer it all to trucks.

You can't run the same cars from Russia to the U.S., unfortunately they're like the only place in the world that doesn't use Standard Gauge tracks and rolling stock (they use 5-foot gauge instead of the standard 4 feet, 8-1/2 inches; oddly the latter actually works out more nicely in cm than the former), but if you did everything in shipping containers it wouldn't be that hard to build a yard somewhere and just shift them across to new cars. Probably do it on the Russian side since you'd want to save the space in the tunnels and go with the narrower gauge.

Russia, particularly Siberia, has a lot of natural resources. Timber, coal, mineral ores, and probably oil ... lots of stuff that's good to ship in bulk via pipelines or via heavy rail.
