How long does it take to bore out a mile with the latest boring technology? How many miles can it cut before major overhauls are required?
The southwest is massive, those locations are hundreds of miles apart with extreme geological features.
No way that is true. The average speed of a TBM is 15 meters/day. The latest plasma cutting technology boasts it can dig 100x faster, which at most is 1500 meters/day, not quite a mile.
From what I read about Alice is that it bore out a 2.6 mile tunnel in about 11 months, anf that is incredibly fast.
Elon Musk owns a massive tunnel digger.

They can bore up to 7 miles per day with Alice.

That sounds crazy to me, as well. I’m sure I have my numbers wrong. Looking into it- again. Will update.
And back in the days when those tunnels were probably built, it was a lot less crowded out west. Now the West is crawling with people it seems.
