When I got there the main straight past 1 was already paved to the South and they were working on the North side toward the hot pit lane.
I noticed that the hot pit lane was ground down where old meets new and this continued for as far as I could see.
I entered at the far west gate. I wish I had my phone or camera with me, but left the house without either.
Since the paving machine has to lay down sections only as wide as it is, I'll bet there will still be a visible seam, although it may not be in the same place as the last one.
