I haven't decided on an appropriate tag, but I went ahead an removed the Crown Point Bridge from the map to keep things up to date. I left the way intact, just removed the highway and bridge tags so nothing gets rendered<http://www.openstreetmap.org/?lat=44.03215&lon=-73.42277&zoom=16&layers=B000FTF>. I also left a note explaining the current situation for the next mapper who edits the area. When an appropriate tag is decided upon, or a new bridge is built, this way can be updated. That's the beauty of OSM! As for tagging, here's how we do roads/bridges that are under construction: highway = construction construction = primary why not use this same structure for closed roads/bridges? highway = closed closed = primary The Crown Point bridge is currently closed. Soon it will be demolished. Then construction on a new one will begin. Because this is the usual cycle, I think the rendering that is used for roads under construction (dashed line<http://www.openstreetmap.org/?lat=44.44777&lon=-73.21343&zoom=16&layers=B000FTF>) would make sense for closed roads/bridges as well. I'l probably tag the Crown Point bridge as under construction right now, but tagging for the renderer is wrong. However, if I did it would be true in 6 months! Actually this road tagged as under construction<http://www.openstreetmap.org/?lat=44.44777&lon=-73.21343&zoom=16&layers=B000FTF>, probably shouldn't be. Construction was stopped on it years ago, so at this point it's just closed. Anyhow, that's a good reason for rendering of closed & construction to be the same or similar. There is a fine line between them. Construction implies it will be open in the future, Closed does not. Subtle difference for the slippy map, but important for the underlying data.
