Absolutely - the restriction is much better tagged on the way. It's a
property of the road just like a speed limit or surface, which we also tag
on the way; and as the 'over' bridge itself is tagged as a way, it seems
anomalous not to tag the 'under' way.

Certainly OSRM doesn't, and can't, parse maxheight on nodes. A quick look
through the Graphhopper source suggests its truck profiles expect way
tagging too, though I'm no Java expert and may have missed something.
