Why in the world would you want to go to "Hampton Beach" on the 4th of July?? Unless you like people, lots of city type people and traffic jams like you never seen before... Oh wait, you said your from Virginia Beach, I take that back. You can't stay at Hampton Beach State Park, you have to get on the list and then wait for someone to die. The better bet is to try to get into Salisbury SP in MA just 6 miles away.
I can help you with local knowledge as I live just 10 miles from the beach and I grew up in the islands in VT (Isle La Motte).
Your best rt. north is to make your way over to 81 to 84 to 90 to 495 to 95. I travel that rt a couples times a year it's by far the best (my father lived in Charlottesville)
