As the Exit 3 construction wraps up, some old pieces are closing and new ones are opening. Once all is said and done, supposedly within a few weeks, we'll need an I-87 point for Exit 3, and might need to move or even split Exit 4. It's still not completely clear to me what's going to remain from the old setup, but I know Exit 4 NB is supposed to be for Wolf Rd SB once the new Exit 3 NB flyover is ready. I'm not sure what Exit 4 SB will ultimately look like.
I think we still will not be able to have graph connectivity for Exit 3 or 4 with New York 155. NY 155 will need a new I-87(3) point at the end of the new ramps, west of the Desmond, but the "3" point on I-87 itself will be somewhere around the new off ramps.
I don't think it's worth changing anything just yet, but it won't be long.
