Is the listed school building (14919003) this one: osm.org/way/988125579 ?

Tullygarran, not Tonavane...

Many thanks!

I didn't add Brow Head, no, I just added the Wikidata reference.

I've just added Burr Point in osm.org/changeset/158215262

It's permanently blocked off now; I was there today and have updated the area.

Checked and fixed!

I drove this yesterday. The directional signage at the southern roundabout doesn't show R744, except for the existing east-west road. However, the distance and destination sign about 50 metres up the road after you've joined it has a little rectangular R744 on it above the large square white sign listing the destinations and distances, if you get what I mean. Having an R road with three distinct ends would be unusual, though.
