If you can, utilize what's there as I have to hook each one of those lines in with the old edges. I suppose you could rework the whole area as well. I dunno. Keep in mind that the line on the right (the blue one) is an inch lower than the 0 level and the red and green lines on the left are 3.5 inches above the 0 level. I'm flexible and open to ideas. Let's see what you've got! I only have two industries at this time... people and a coal mine. EDIT: also, this area could be viewed from both sides if necessary. That's kind of what I had in mind for the curved collonade bridge on the top left.
