JMHO _TappanZee to GSP to NJP to 95. Take 695 around Baltimore using Key Bridge or the norther route (think that is called “west”). Avoid any perceived short cuts unless you don’t mind stopping for many traffic signals. I tried it once going to Fredrickburg VA. It was a route through Delaware, 13 i think and it was the worst choice i made. Sure its laid back and some of it is scenic but not very efficient if you are trying to keep to a schedule for your vacation. Might be good for some but from now on it is 95, 83, or 81 to the south out of the northeast.
