Well, the fat lady ain't sung on any of them yet. Looking at Canada, and now North Dakota, Tesla has changed their construction techniques for Supercharger construction for chains of locations. All of the sites from Eastern Alberta to the Western Ontario border have been partially built (mostly by the same crew), but with power inspections not yet done and pedestals missing. I would think that this part of the process can be done quickly. We've been pretty much assuming that there is a pedestal shortage, or V2/V3 secrecy, or there is some other constraint, but it is possible that they want to get the lengthy part of the construction process out of the way before the ground freezes and spring a massive surprise opening on a string of Superchargers in a few short days.
In the context of this supercharger, it is possible that the groundwork construction will progress from Dickinson to Alexandria, then the pedestal work will go East to West. We also don't know what is happening in Montana, except for maybe a few privileged individuals (cough,
@lightfoot3b, cough cough) that aren't saying.
Either way, I'm pretty happy to see the progress being made and I can hear
Brünnhilde warming up in the next room.
