It looked like they were laying new pavement between T-4 and TBT. This was going on all last week and still going on this week. The affected gates mainly appear to be 41 & 43, but I was surprised to see this. Luckily, my flights last week (LAX-BOS) and this week (LAX-BNA) were even numbered gates on the opposite side and unaffected by the construction. But any mainline flight that has a 44 on it, you were being bused to an area east of the terminals (down by where you usually take off, not west - down by the Eagle satellite terminal or maintenance hangar). I don't know how long this will be going on. Hopefully, my coming flight this week to JFK won't be affected either.
