I'm having trouble getting the right render for the tertiary roads and service roads look in my map render. I'm trying to get road edges like in the old USGS topo maps:
Notice how the road interior is empty. You can see boundaries and contours through the road. So the trick of using a thick white line with two thin dark edges wont work for me.
So I set up two lines with offsets in opposite sides of the road. My version shows overlaps between road segments:
The rendering in QGIS is incredible, so I'm wondering if there's a style approach that I haven't discovered to get the appearance of connected road edges.
