I have a tip for this one!! Go *around* the toll plaza. Check out Google Maps to figure out the route, but from the North, you would exit from 95 around exit 3 or 4 - then re-enter 95 after you get past the toll (in Maryland).
Last time I did it I just dumped out on a lark and there were some Detour signs taking you back to 95. Not sure if it saves time, but it certainly saves on the frustration of being trapped in traffic (which I hate).
