Indeed, only Joyce Kilmer (East Brunswick) is closed at the moment. Best I can tell it's supposed to re-open in June of this year. Any other ones that haven't yet been rebuilt will probably be closed shortly, but I can't keep track of which ones have been finished. The only info I can find about details is news stories from last August, all of which imply that James Fenimore Cooper and Walt Whitman are supposed to be under construction now, but they aren't. I think Walt Whitman is already finished, but no idea about JFC. They seem to only be closing one at a time in each direction.
I also found an article saying that there is a plan to put a large number of EV chargers in every service area on the turnpike and Garden State Parkway. Nothing about how many would be Superchargers vs. CCS, but I would expect both. Apparently the concessionaire has recognized the benefit of providing fuel for modern cars!
