odd - and reflecting current usage patterns as far as I can judge
from analysing current data. Even odd rules can be quite useful.

Thinking more about it, perhaps location=* would be a good alternative
for tagging very long bridges and tunnels?
Thinking of bridges spanning whole valleys with towns bellow them and 
similar. Working out every crossing that may happen to be bellow the
long bridge and how it relates to the underground railway network down
there is impractical.
