Ok, roads have kinda ruined my game.  Is there no way to stop constructing a road?  It would be nice if it would pop up and tell you how much its going to cost in the long run to connect 2 cities.  Also seems that they build the road the LONG WAY AROUND to places instead of point a to point B, can't they build over a mountain?  I think maybe there should be an option albeit expensive to build over a mountain, or an event where caves might be found in a mountain that can be used for passage.
