thank you for reviving this. Bridge details are really a problem right now.

I think we could also keep typology in bridge=* like we do for buildings,
but if there was a majority for bridge:type I had no problem either.

+1, I'd drop culverts from the bridge tagging, they are underneath


Maybe we could also add some key to distinguish the kind of material of the
structure, e.g. masonry, riveted steel, iron, wood, ...?
