Thats a problem with the layering. Generally abutters and landuse are
drawn first, but in this case there is a bridge which has a higher layer
and by definition everything in a higher layer is drawn later.

This is a good case to show that having abutters tagged on the road
instead of a separate landuse is problematic. But there are so many
problems surrounding layering etc. that my head hurts every time I try
to think about it. :-)

I don't have a good solution for all this.

Workaround: Tag bridges as unclassified instead of residential.
