Styling all roads to highlight their outline?

I don't think that what you're trying to do is possible. I played around with the styling wizard, and it appears that despite it appearing as if there is an outline on arterial and highway roads, there's isn't really or it is not visible after applying styles.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
