You're welcome! I left the way there, changing it to highway=disused (not sure if that's an actual tag) with a note saying that the ramp was removed. That way, people won't add the ramp back.

The ramp you added from WA 16 to I-5 NB does not exist anymore (satellite imagery has not been updated to reflect this). This interchange was completely rebuilt several years ago. I will be deleting the ramp you added.

Suggest you change the new HOV ramps at the I-5/520 interchange to highway=proposed. They haven't been built yet and construction hasn't yet started. Also do the same with the bus ramps and the Montlake Lid.

I don't have the slightest clue. Go ahead and remove it if you want.
