[roads] Lingering Bridge layering problem on zoom 13 in mapnik

Description

Back in o26009, the bridge layering problem was addressed. However, it seems that it wasn't fully fixed. It seems on layer 13 that "motorway" bridge's are rendering on-top of other bridges.

Here's an example of this: Here on zoom 17, Townline Rd is rendered properly overtop of the QEW as it's on layer 2 and the QEW bridges are on layer 1. http://www.openstreetmap.org/?lat=42.96323&lon=-79.02229&zoom=17&layers=M It looks fine on all zoom levels while you zoom out until zoom 13 (the last zoom you can see tertiary bridges). http://www.openstreetmap.org/?lat=42.96323&lon=-79.02229&zoom=13&layers=M

Is it possible that you can fix zoom 13 fully please? Thanks.

The first zoom where you can see tertiary bridges is actually z14. This means that at z13, the tertiary bridge is drawn as a regular tertiary and then the motorway bridge is rendered on top.

As it is still quite noticeable, perhaps a proper z13 tertiary bridge is in order.
