Yep, that is what I was originally doing, but I broke it by purposely
combining all road layers to make joins between roads with outlines
looking much better (which Thomas' reply referred to).
As part of that change, and in order to improve visual effect, I decided
instead to use ground relationship to split roads into three layers,
resulting in tunnels under surface roads under bridges. I figured I
could tidy up the side effects if I could just get objects within the
layer rendering in order of road importance. :-)
I will try playing with ordering in the DATA property as Thomas suggests.
This works perfectly, so now I'm 95% there. :-)
One last problem I'm scratching my head on.
I want to highlight bridges by using a thick border on each side of the
road (and if possible an angular section at each end of the border as
often seen in traditional road maps). Using an outline won't work for this
as outlines close the end points of the line segment with a border and I
would prefer them to blend directly with the road to which they belong.
I'm thinking a symbol would be needed but not sure how to approach it.
Like (view this with a fixed width font):

How to achieve such a border?
