stephankn, thanks for the update.
I guess you’re referring to Motorway 6, which is the only major under construction highway I remember recently adding. Actually I initially tagged it as highway=proposed, but someone changed it to highway=construction. That isn’t incorrect, though. Construction has certainly begun on the ground, in certain segments of the road at least.
Usually I make it a point to leave under-construction roads dangling, since in reality the connections don’t yet exist, and adding them early would involve guesswork, which could very well turn out to be incorrect. This could turn into a problem if someone updates the tags from construction to completed without checking the connections. That’s something the tool would certainly help with.
The way I see it, under-construction highways are a persistently open issue unto themselves, but one that can’t be immediately fixed and closed—they’ll need eventual updates as work progresses. Ideally we’d track them separately, but I don’t think there’re enough highway=construction tagged ways to warrant the work. I’m just a bit worried that someone might try to “fix” the dangling ends and add inaccurate connections, turning the open issue into a falsely resolved one.
