about line joins and their z-order

I've rendered a map image like this: http://www3.mapasia.com/jackout/rj.png
there are a few problems here:
1. they are joined correctly
2. although they are joined, but the yellow one should "covers" the white ones
3. the white one should be drawn beneath the lower segment of the yellow one
As trying to fix this kind of problems, I've noticed that it's impossible to control the z-order of how roads are drawn. Say, in may cities, one very long road may elevated somewhere, and dive beneath other roads somewhere else. Is there any way to present this kind of thing with MapServer?
