I was wondering - isn't the blasting mostly done for the single lane highway that is there anyway? Couldn't they just twin most of the existing road in the current right of way using concrete or steel cable barriers in the centre (when narrow), and just build bypasses around the towns that it passes through?
I know that up there it wasn't built like a super-2 with everything ready-to-go if they wanted to twin it someday, but I would think that much of the tough stuff was done years ago when it was first built, and that in the unpopulated stretched you don't really need a new alignment at all, and you can just build a second road alongside what is there in the existing clearing.
