I've posted a photo from Holborn Viaduct before, but this one is on the other side of the road.
I've been taking photos but recently have been a bit lax in uploading them so I may have to post a couple a day to catch up! I won't do an avalanche at one though, I promise.
It happens to all of us sooner or later and thank you for being considerate and not posting them all at once. this one is a fascinating subject and perspective
