Elon Musk Says He Has a Green Light To Build a NY-Philly-Baltimore-DC Hyperloop (theverge.com)
An anonymous reader shares a report:Elon Musk just tweeted that his Boring Company tunnel project has just received "verbal [government] approval" to build a hyperloop connecting New York City, Philadelphia, Baltimore, and Washington, DC. While we work to verify his claim, Musk is continuing to tweet more details about the project. The hyperloop, an ultrafast method of travel first developed by Musk in 2013, would only take 29 minutes to travel between New York City and DC, he claims. And it would feature "up to a dozen or more" access points via elevator in each city. Update: Eric Phillips, press secretary for the New York City mayor, tweeted, "This is news to City Hall," adding "The entirety of what we know about this proposal is what's in Mr. Musk's tweet. That is not how we evaluate projects of any scale."
I doubt anyone in the government verbally approved a project that is likely in the hundred of billions...
Yes it's an anecdote! Were you expecting original research in a Slashdot comment?
Fortunately, there is almost nothing underground in NYC.

"The hyperloop, an ultrafast method of travel first developed by Musk in 2013"
By "first developed" you presumably mean "applied some minor tweaks and a 'cool' name to a basic concept that's been around for over two centuries"?

Certainly Musk might end up being the first person to get a practical vacuum tube transportation network working, but crediting him with developing the idea himself seems a bit much.
This Space Intentionally Left Blank
So I have some friends who are of the belief that Musk is just a consummate shyster, and I have disagreed, pointing to promising results with SpaceX and favorable sales from Tesla. This kind of talk makes me believe that there might be something to their concerns. I assume "verbal approval" from the gov't means that he asked someone (who knows who) if in theory he could do this and they said "sure", which counts for all of nothing. What this doesn't sound like is the well-established plan of an enterprise that is going to go forward.
This seems to be the one route in the US where a train service can make money so it's no surprise that he *wants* to build this route. If he could bore under existing railway rights of way, it should be a relatively simple project from an administrative standpoint (no worrying about easements et cetera). The tracks would then carry only freight and the number of tracks would be reduced in favor of green space and walking trails. Amtrak would go bankrupt and there would never be a public train service in this country again. I'll let others opine whether this is good or bad but certainly would be the outcome.
But no president of the US of A will never say something like that.
A president has a value for his word. Because he is trustworthy, reliable, and does consider the implications of each word coming out of his mouth.
New York City is built upon the North Atlantic Plate, a mass of solid rock extending from Canada and whose nearest boundary is in the mid Atlantic. The skyscrapers of the city have their foundations on that rock. It is difficult to imagine how the Boring machine would penetrate that mass. Certainly not at the affordable cost that has been mentioned here.
While there have been smallish earthquakes in the area, a tunnel through solid rock should be relatively immune to such disturbances. Tunneling through California might be more of a risky venture.

Branch off the main line for the elevators. Like a pitstop. Then all you have to do is make sure there are no collisions coming out of the pitstop back onto the mainline. And that's technically trivial.
Not if you dig deep enough. I mean yeah, a 5-minute ride in an express elevator at each end does increase the total travel time considerably, but it's still a lot faster than driving.

I would assume the elevator doesn't actually intersect the main tunnel, but rather an underground station/siding where loaded cars would then wait for an opening large enough for them to merge into the through traffic.

Approval needed from: Federal DOT; 6 states; 17 counties; numerous cities; hundreds of elected officials. Definitely happening rapidly. @yfreemark
The fastest and most efficient mode of transportation is falling.
Yeaaaahh, that's true. But it's _really_ deep. The water tunnels are 600 ft down, and there are subway stations as far down as 180ft (with very trouble-prone elevators).

There are flying machines that can whisk you between coasts in about six hours. I know it sounds like science fiction, but it's true. It's even safer than driving! Even better, there are also options for stopping in cities BETWEEN the coasts! There are even well-developed electronic systems for procuring travel tickets at times convenient to you!
It is easier to get approval to send men to Mars than it does to build a tunnel from DC to NY.

Space travel doesn't cross state lines.

Of course Elon Musk didn't get verbal approval for the entire track. Perhaps he had the merest hint of a suggestion from someone (DOT? Two people on city councils at either end?).
Getting actual approval from all the different cities, states, counties, and regulatory bodies involved will be an enormous undertaking. The fastest way to get this sort of discussion happening at all of these levels is probably to... force people involved to deny it.
A single tweet and suddenly you have multiple nationwide news articles and, most critically, everyone responsible for approval at every level talking about it. They're talking about it to nail down who said, but they're talking about it. As are all their constituents and peers.
The largest hurdle when dealing with so many people in authority is simply tendency toward inaction. With a tweet, he has solved that. Forcing people to say "he won't be approved without following the process" removes the option of sitting on it silently whether out of apathy or to gain leverage.
I'm trying to stay concise, but I'll spell it out for you.
NYC has a TON of underground infrastructure that goes down as deep as 600-800 ft (depending on where you are and how you measure). For a train traveling 700MPH, you are going to need to pick a depth and more or less stick to it over a distance as small as Manhattan (maybe 3 miles wide at most?). The higher you go, the more trouble you will have finding a clear straight run. You can't get too close to the infrastructure above, or the rock will not support the weight and you'll have to make expensive reinforcements. For instance, when putting the LIRR (Long Island Railroad) connection in at Grand Central ("East Side Access" if you want to Google it), they opted to dig 140 feet down so that they would not have to reinforce the foundations of the station above. The F train is about 100 feet down so it can pass under the other subways. I can tell you from experience that the escalator ride is no fun down to the F train, and I would avoid it if I could. Sometimes the escalator would be out of service and you got to use them as stairs. Fun. There is an infamous subway entrance at Washington Heights 180ft deep that is accessible only by elevator (well, also stairs). The elevators are troublesome and one of them has - I shit you not - a human operator who just sits there and presses the automatic buttons. The other (identical) elevators are fully automatic, they just still hire this one guy. Sorry, tangent.
Finally, there is the water infrastructure. It is the deepest as far as I know, down something like 600ft. Maybe there is some way to "thread the needle" and get the hyperloop tunnel between the water infrastructure and the subway infrastructure. That'd be great, but it's still really far down. If he can dig all the way from Washington to NYC it will seem like a relatively minor thing, but lets not pretend it's trivial. It took them 4 decades to dig the water tunnel.
