[OSM-talk] Proper use of layer tag with the Mapnik renderer?

[Michal Migurski]

Hello,

I've just made some edits to this interchange:
	http://www.openstreetmap.org/?lat=37.819252&lon=-122.25409&zoom=18&layers=B000FTFT

I've used the layer tag in what I think is the right way, but the  
Macarthur Blvd overpass (layer=3, bridge=yes) is now being shown  
underneath the I580 overpass (layer=2, bridge=yes). Seems like layer  
should be fairly unambiguous, why wouldn't it be able to draw the  
overpasses in the correct order? Did I mistag?

Here's the same spot from the air for comparison:
