Those signs were installed when the works started last year. I have no idea if they are permanent, but I doubt it. There were bags on some of those signs like here - https://www.mapillary.com/app/?pKey=559230242731912&focus=photo. My best guess is they got torn off. Technically, I guess currently no one is allowed there because signs are visible. And the works technically aren't finished, even if the surface and main portion is done. But practically, literally everyone is ignoring them. I guess I wouldn't retag access here until the works are complete and see what the signs say then. Are you proposing to retag something for now?
