You won't need to use branches to prompt re-orientation if you're moving them 3 hours away. Just remove the screens (if you;ve used them) and let them out ASAP.
Personally I would move them at night, after they are all in, using a pick-up truck. Ratchet-strapped six-ways to Sunday, placed so they are riding along the long axis of the truck, not cross ways, though in an established hive with drawn combs, this is probably not as critical as in nucs where the frames could slap around a bit.
Have a plan to get them roughly in place at the new location just before dawn, maybe not on stand and perhaps just set down close to their new yard - you can tweak them to the right sites in the few days afterward. If you screened them in before the lift into the truck, I would pull the screens on arrival (after a wait to settle them down if the last part of the trip was jostle-y), then take a nap and get up and get them off the truck.
And remember, you may have different challenges in PA than in CT, including maybe bears, which might need fencing-out right away.
I don't know whether you need to have them inspected in CT before moving them to PA.
