It's supposed to end on 3rd september, and tart this saturday.
I'm using the taxi:no tag because my software uses that and i uild maps to use eah weekend. I didn't want to close it properly before saturday and have the roads reopened by someone else.

ive found some new articles abut the closure, such as at https://insidecroydon.com/2023/05/11/ses-water-works-will-close-main-a22-for-six-weeks-from-july/

but one of my customers, a taxi company in purley, talked me through the dtail of the closures over the phone .

We have a customer local to that area, who says that section of the road is called leopold place. Other mapping sites seem to confirm that.
