I didn't find way/345799923 when I was walking to the station on 20 September but maybe I'm blind or it's changing daily.

FYI, I partly undid this change in changeset/34578668 because it appeared a few unrelated nodes got dragged around, relocating Oreillys Road and a house-number line in Karen Crescent.

Thanks for sorting this out!

Rode through this area at 7 pm on 2015-06-12 and the road in question is in place, not blocked, not under construction.

Did you mean to delete the street right of way for Tavistock Place / Tavistock Square? Only the bike path is left now.
