There is a reference to Philadelphia on the Garden State Parkway Southbound in Woodbridge or Metuchen just before the exit take you to Turnpike interchange 11. South on the turnpike 30 mention of Philadelphia until you reach what used to be the Pennsylvania Turnpike extension which is now the new 95 South. That's where Philly references appear. It's been a painful years but last I remember most control City Signs continue to say Del Memorial Bridge or Camden. NB on 95 now says "New York" as of new signage.
