Excellent point. Not sure why I tagged it like that

Any reason to use turn restrictions instead of making the road a one-way?

I copied these shapes from a chapel hill open data kml file and thought I'd removed the gis tags from them all but clearly missed those two. Thanks for fixing them!

OK, I see what you're doing, and I agree with it. I had experiences in the past with people deleting 10s of miles of abandoned railroads that were still obvious, and thought that was what was going on here. The segments you are removing are obviously completely gone, and should be removed.

You can't tell if these are gone without also looking at terrain data to see if any trace of the changed terrain exists. Abandoned railroads are very useful to have in OSM, even if the tracks are removed because it's not about the tracks, but about the corridor that still exists and still feels like a railroad corridor. I use this data a lot and don't like it getting deleted for no apparent reason.
