NY TacStaPkwy: Pudding Street grade separation (PudSt -> 28)

[cl94]

The Pudding Street intersection along the Taconic State Parkway in Putnam County is in the process of being grade separated. When the interchange is complete, Pudding Street will become Exit 28. As of today, no exit number is signed, even though 3 of the 4 ramps are in use.

Given that it's a relatively minor intersection, I expect that few .list files will be affected by changing "PudSt" to "28" once the exit number is signed.

Per the log, no one is currently using PudSt.

If someone were it'd be preserved as an alt label to not break the .lists of anyone using it.

It looks like this project is completed.  (https://www.pcnr.com/articles/residents-celebrate-opening-of-pudding-street-overpass-on-the-taconic/) (requires subscription)  Has anyone been through there to see if the exit number is signed?

Just drove it today, it's signed as Exit 28 both ways. All the ramps are now open.
