Here are the ones that I think are worth considering:
- Opening or swing bridge ahead
This is already covered by the approved tag bridge:movable and its
various sub-keys that describe different types of movable bridges.
For the swing bridge, it's covered. But the text says "Opening or swing
bridge."
I have no idea what an opening in a route might be if it's not a movable
bridge
but maybe somebody else on the list does.
Lift bridge. Has a horizontal axis for the moving part, which moves vertically.
Think of Tower Bridge,
As opposed to a vertical axis so that the bridge roadbed can swivel in
the horizontal plane. That would be a "swing bridge".
Both are "opening bridges".
- Hidden dip
Maybe. There is a barely used tag hazard=dip. Is this a permanent feature?
I don't know. I don't recall ever seeing that sign. But in my part of the
world we have old hump-backed bridges so it's conceivable we have
roads with hidden dips, too.
It's a hazard you want to know about if you are a car driver thinking
of an overtake. "don't do it; an oncoming car might suddenly appear".
