OpenStreetMap 開放街圖
Today I was thinking what to do with a Motorway junction that has been torn down completely more than a year ago (if I remember correctly).
In the end I deleted it from OSM. Was that OK?
Here is why I decided so: I know this junction will never be the same. The old bridge doesn't exist anymore, and 2 new bridges to form a big roundabout on top of the motorway are in the EARLY phase of construction. From what I can tell, the whole joint between Ronda De Dalt/C-32 and A-2 will be different, too. So the whole routing of cars coming and joining A-2 will be different.
As soon as the new junction is up, I'll make sure to GPS track it and add it into OSM again ...
so long, Kai

Yes, deleting non-existing ways is ok. But if the motorway junction is still visible on aerial images (e.g. Bing), best is to leave a way with no attributes except a note telling that aerial image is out of date. Otherwise someone else will trace the motorway junction again ...

Oh as well use the construction tags as well
highway=construction
construction=(motorway, motorway_link, trunk, primary, ...)
