The road outside work is rutted and potholed. There's trucks coming past
all day and night, local residents can't sleep, you have to wonder how
much shaking a building can take before it falls down.

So a letter came from the council that a stretch was going to be
resurfaced, i'm noting from my office window that this is happening, yet
nothing has been dug up.

Is there any danger this will be more than a temporary fix?

I'm guessing not. An educated guess.
