Looking good buddy. I need a bridge for my embarkation into VBCW. Roads, hmm. how about some floor tiles from the pound shop (or equivalent) the ones with an bubbly pattern on. Cut to size sprayed and detailed. I'm going to try it once they get them in at Wilkos of Poundland.
They look great. Perhaps some FoW or 15mm roads and rivers would do the trick?
