Yes, I've tried this method.  It looked kind of OK, but not to my liking.  In reality,
the paint on a brick road is usually not solid.  It is usually only painted on the top
of the bricks and is
usually quite worn off in many places too.  The worn look is easy enough, but the
paint crossing the gaps between the bricks is bothersome.  I've tried creating the
boxes for the lines, then
intersected them with the road and raised them up in the y direction a tad, but then I
had the texture of the road on the boxes due to the intersection.  Grr.  I may just
have to create a no-texture
copy of the road just to use for this purpose, even though it'll hog more memory.
