BTW I hope you don't tag all bridges with level=-1 in real world mapping???</pre>

All the bridges I have tagged are layer =1 or more.</pre>

None Of the bridges I have tagged are 'indoor' (so far) so a level tag is not used as in NOT required. </pre>

level=-1 is lower than level=0 or level =1 </pre>

yes, that is logical. It would require adding the information whether it is
right or left from the center of the road and renderers and other tools
learning how to cope with it.
Does it work in practice?</pre>

<pre>
As the node for the object (bin, light etc) should not be on the road (as it is not) the information for the render is already there. </pre>
