As a curiosity, does the Garden State Parkway have control cities? I know of ones at the Local-Express split, but I'm unsure of any at major interchanges, with the GSP merely signed as "Parkway North" or "Parkway South". I'm not even sure if control cities are used at the entrances. For what it's worth, here's what I think control cities could look like:
South of Exit 38: Atlantic City (NB), Cape May (SB)
38 - 80: Toms River (NB), Atlantic City (SB)
80 - MP 104 (Local - Express split): Wall (maybe Asbury Park?) (NB), Toms River (SB)
Local - Express: New York or NJ Turnpike (NB Express), Middletown (NB Local, 104-114), The Amboys (114-125); Wall (SB Express), Middletown (SB Local, 125-114), Asbury Park (114-105)
125 - 145: Newark or The Oranges (NB), NJ Turnpike or New York (SB)
145 - NY Line (172): Albany or NY Thruway (NB), Newark or The Oranges (SB)
No reason to sign the Thruway for New York, so I chose Albany. I could probably have better choice for Local - Express, as the Parkway doesn't go through some of these cities (namely Asbury Park). Finally, I wasn't sure if I-195 or Wall was more recognizable, but Wall won in the end; it felt more recognizable than just I-195. I'm aware the Turnpike is I-95, but it's recognizable enough that it does make sense as a destination instead of I-195.
