Highland Road is a good looking map. I like how you captured the feel of a bridge, without actually having one.

My one concern (without having built it) is the imbalance of the glyphs. If they could be shifted 2 spaces alobg the edge of the map towards the middle there would be a lot less worry about drawing mismatched glyphs. You'll need four single hex tiles to build up the edge of the map a bit to maintain glyph access for double-space units, but if you have them available, or can free them up, I think that little change will make this map even stronger.
