Better traffic in northeast friday or saturday?

I am going from Boston to Central Virginia next weekend. My question is which day, Friday or Saturday is better to travel, traffic-wise? I will be leaving Boston around 7am so I would NY area by around noon and be well into Pennsylvania in the afternoon. So which morning around 11am is traffic better in NYC area?

Other answer:

Paul:
Definitely Saturday. Traffic is far worse on weekdays (especially in cities) because more people have to go to and from work. Good luck! 🙂

Saturday for sure, I-84 might be a good alternative route to avoid NYC traffic, check your map.

FYI: Hope you have an ez-pass.
