Going from West of Boston to Andrews Air Force Base

RVER I am not as familiar with the northern part of your route but most of my adult life was spent in the Baltimore/ Washington area. You won't go wrong going the 301 route but miss it all going out to Harrisburg.

I generally will take I84 to I684 to I287 (tappenz/mario cuomo bridge)

Off I287 I will pick up connecting interstates going west.

ferndaleflyer tha last route you suggested did not avoid GW bridge in NY which is HORRIBLE given it takes me down 95 without avoiding the George Washington Bridge. Should be able to Go 95 and then jump up and around the GW bridge but not sure. My best atlas is not with me, it is in my RV so have a really old map and having trouble finding a way around but maybe not so maybe have to go 84 to 81 but seems to really going out of my way to get to Andrews. IF someone has a work around before 8 this morning, PLEASE let me know, otherwise wish me luck!!
Thanks all for your suggestions, knew my RV friends would come through. Taking the car not the RV but still horrible at the GW bridge.

81 t0 83 at Harrisburg--83 S to 695 west to 295 (BW Parkway to 95 S to Andrews. Better yet, 95 to Del memorial bridge and hit 301 S to rt 50 west to 95-495 S to Andrews. That going to 70 is probably 60-70 mi out of the way.
