@Benie – sure, here is an old map I had used for planning purposes.
Disregard the different coloured segments. I have a placeholder deed at each of the two X's. There are undeeded inns at the points marked along the route. The highway is finalized and catseyed west of Esteron as far the black X deed, paved and passable to the white X deed, where I am currently surface mining down a steep hillside. Once I've bridged over to the kidney-shaped island, I intend to set up a final, semi-permanent deed there as a base to build the series of bridges from, probably with a wagoneer to make moving materials easier.
