Also apparently AADT on I-95 north of Bangor is only 3K...

I agree that an interstate freeway towards Calais would have been more logical though from an economic standpoint.
Ps: I just checked the map. Lol Loring A.F.B.’s actually closer to N.B.-2 if anything.
Ps: Is N.B.-2 the only Canadian freeway that runs along the border for a substantial distance? (No, the undivided-4-lane portion of Crowsnest Highway in B.C. doesn’t count as a freeway lol.)
