The rest area at exit 17 has been under construction. I'm not sure if there are porta potty's there. The old building with the bathrooms has been leveled. This past weekend the rest area was open but i'm not sure about bathrooms. You can get off at exit 17N and take rt 9 north maybe 1/2 mile and there is a Dunkin Donuts on the left. I'll update this thread later this week. I have to back up north later this week.
