Please see below the official notice of part of Slade Lane being closed on the 17th Feb.

Its a bit jargon-heavy, but the gist is that it’s the other side of the junction from us, so if you’re heading towards the river then you’ll need to go a different way. See the image below. They say this part will be closed for about 24 hrs, so they are expecting it would be reopened on the 18th, possibly the 19th if things take a bit longer.
