That's called an immersed tube tunnel. The way it's done is they dig a trench at the bottom, lower concrete tunnel elements to form the tunnel and then cover the structure with rock and sand. This method has been used many times in the past and will be used in the future, for example here:

Immersed tunnels aren't always cheaper than boring or blasting through rock. For one thing, it is cumbersome and expensive to dig a trench in deep waters.

US military application of existing GPS satellites can already achieve fixes down to 5cm. Centimeter-accurate positioning will never be allowed for civilian use, no matter how many satellite constellations you put up there.

I don't know about that. Is there anything malicious that a person could do with centimeter positioning that they can't already do with meter positioning?

Hell, I doubt that that there has ever been an instance where someone has managed to commit a crime because their GPS was meter-accurate, as opposed to for example 10-meter accurate or 100-meter accurate.

If I'm not mistaken the accuracy restrictions are mainly there to prevent foreign forces from developing munitions such as these:, but those restrictions will be extremely difficult to keep up when Russia, China, EU and others (India, Brazil, etc) have fully operational satellite constellations. You will pretty much need to get everyone to not compete on accuracy while there will be massive demand from the market for things like more accurate autonomous vehicles.

I wonder how long it will take for the magnitude of that achievement to be noticed, let alone to sink in with T.C. Mits. I have a feeling that it will get mentioned, and Bill Nye will share a few words on CNN, but that it won't get much play in the mainstream press. We'll find out soon enough, I guess.

Keeping fingers crossed... ;-)

It probably won't, but the fruits of it will be noticed. I think the general public will like ubiquitous cell and data coverage, even in remote areas, or centimeter-accurate positioning. All of this stuff will be worldwide by nature.

Those are just two things that would be possible if it was cheap to launch and maintain thousands of satellites.

Yeah, tell yourself that.

The same person who hits 100 sequential bulls-eyes at the shooting range is rarely able to hit a barn wall from ten yards in a real life and death situation.

Also, the government tends to use body armor and automatic guns.

Sigh. This is how it works:

In case you've been living under a rock for the last 14 years, they already have a war with the West/NATO.

In a somewhat ironic turn of events, Muslim fundamentalists in countries like Afghanistan, Pakistan, Iraq, Syria and Gaza now have an actual real honest-to-science angry skydaddy with winged creatures that shoot fire from the sky.

Of course, this does not really bring us any closer to peace with the Islamists. If anything it probably helps them recruit.
