D, come down 84-87-287-78-476-95, depending on the time of day 476 can get jammed up, avoid rush hours. Otherwise DC is a non issue these days, many new highways through there. It gets backed up during rush hour in Quantico VA south of DC, If the express lanes are open south bound use it.
hope you have an EZ PASS.
When we lived in PA that was my only traffic jamb in VA, I would come through there after 7pm, or between 10 and 3 otherwise no issues.
STAY AWAY FROM THE GW BRIDGE. That area is miserable and the toll charges are extremely expensive.
Maryland is an exhausting drive, the scenery doesn’t change so you feel like your driving in circles.
you could come down 84-81-77 through Charlotte and cut over to 95, that will add around 100 miles, there’s nothing but a VERY LARGE MOUNTAIN, to climb up and go down on 77, Very scenic and beautiful! You will avoid Philadelphia, Wilmington DE, DC, Quantico. Depending on time and the added fuel cost. I can tell you that mountain is a tough one, went up and over it in my wife’s Ford Explorer several years ago, it struggled, never tried it in either of our coaches. Been down 81 more times than I can count headed to Tennessee.
