If health and safety are the top criteria to determine spending, then it seems like paved roads would have to be pretty high on AC's list. As high as a bridge, I would guess.
The cobblestone that has been laid in some areas is very nice. To me, those roads do not suggest the impending doom of 'progress', just a community that cares for its environment. Hopefully maintenance is reasonable, and those roads can be kept up.
