It's K38 - the Box at the junction of Silvertown By-Pass Road & Connaught Road in Silvertown.
The road on the left is Connaught and the one on the right is the By-Pass Road that goes up and then left across the bridge over Connaught, which itself continued north to a swing bridge connecting Silvertown to Canning Town. The ship in the background on the right is at the Royal Albert Dock. The Silvertown Train Station was right behind the camera position.
Connaught Road is still there, but the By-Pass isn't, and almost everything in the area has changed rather drastically.
Edit: Topic renamed, moved to Metbox Catalog and tied to the database.
