This is the strangest, most bizarre, most irrelevant overhead sign I've ever seen in the state of New York. In addition to several questionable aspects of the design and layout and the fact that it skips over an intermediary exit, it is completely unnecessary. It doesn't provide any new information of value, and there is not one single reason why it should exist.

I'm questioning why almost every BGS design was used for the I-81/88 interchange. You have the APL linked, then a Junction sign with no arrows, which imo should've been in the APL's location, then a diagrammatic, then finally, the 2 panel display with angled arrows for the exit. Can they pick one type and stick with it?
Yeah, it leaves a lot to be desired. The APL I originally linked to went up as part of the I-81/I-86/NY 17 (
Prospect Mountain interchange) overhaul, while the other 3 in your post are all much older and should be replaced, IMO. NY uses APL's now, so if these were replaced, the diagrammatic would presumably become an APL. And yes, it is ridiculous that the "JCT I-88" comes after the APL... even though I have some serious issues with the APL, that 3/4 mile advance should probably be eliminated altogether.
I'll follow up in a separate post with some of my own suggestions for improved signage here.
