As I mentioned before, the first piece was free.  I hadn’t planned for a time lapse.  I had no idea I was going to time my visit for when this happened, nor that it was going to happen so soon.  However, I was there with the camera on a tripod so I manually shot a sequence and cut it together.  It is short but you get the idea.  I left town shortly after this so missed the new section being put in place.  I shall hope to be around when the second span is worked on.
