Building Bridges at Gipsy Hill - part 3

It's been over a month since I last reported the rebuilding work a Gipsy Hill station. (Here and here.) Not much has been happening since. The new footbridge is still in place, but still doesn't have any walls or ceiling. The men in orange jackets are still doing fiddly little work on it, but don't seem to be in any hurry to add the big stuff.
