With the West stand cladding almost finished there are a couple of new cameras for the East Stand about to come online, someone on SSC got a sneak preview...
I think this just means that shortly (maybe by the end of the week) the south and west sides of the stadium cladding will be complete and the main action to the outside of the stadium will be the east side.
On the East side at least 75% of the main framework is in place and there has been more added in the last few days so by the end of the week it'll be about complete, so just the infill framework to do and cladding. I'd guess if all the crews move to the east side it'll be just about done by end December (assuming no 2 week Xmas break) or early January
