Triple A route is basically taking I95 from the GSP to Florida. I695 is the Baltimore Beltway. You have a choice going around Balto either to the east (Key Bridge) or the slightly longer west side. I95 runs through the center but you can't take propane through the tunnels. I495 is the Wash DC Beltway and I95 follows the same path around the east side. 'Tis a lot of numbers. Personally, I'd take I78 to Harrisburg, I81 to Winchester then I66 and US17 to Fredericksburg and then I95. Hope you enjoy the trip.
