I am from NJ. Is there really a reason you are going through NJ???? Miss all the crappy traffic of NJ and metropolitan area and enjoy your trip. I now live in NY state and will at all costs not travel through that state but around via PA when we head south.
Route 95 on coastal CT can be congested as well but there are things to see there...like Mystic seaport (go on weekday less crowded).
Do yourself a favor and avoid NJ...I don't think you will regret it.
If you want to NYC sites you can still ask for route to get you close to there.
