Hi, we're coming into central Philly Friday from the north ... & usually Rt.76 to 676 is ridiculous on previous visits (it's been over a year now) when we arrive between 3-4pm ish. We always hope to avoid the heaviest of the rush hour, but apparently this is the norm on Fridays?!? Since it would be hard for us to get there any earlier than this, would it be worse if we waited and tried to get thru this area say around 5 or 6pm ?? or better? We're not used to big city driving, so it makes us quite nervous. Just wondered if someone could offer any advice. Thanks!
