I just 'Mapquested' it and they say 16 hrs 43 minutes....
NJ is a long narrow state, and Bridgewater is in upper central Jersey if that makes sense.
Even Jersey is hot in August, so know that if you have your furbabies, you won't be able to leave them in the car that time of the year. They can overheat and die in a matter of minutes!
As you get closer to your trip let me know. I live in Jersey, moved here from Florida, and my family is in South Carolina, so I can give you good feedback on places to stop.
