Re: Official Civilization V Feedback Thread
there are fewer auto-worker settings for some reason. it appears that the workers are either on auto or not, and that they will roads and improvements as needed (and maybe according to the city "focus" if you have selected it in the city screen, though i'm not sure about that).
you can also have them build a road to any hex fairly easily. but no, there is not a "build roads" only option for the workers as far as i can tell.
