Providence to PA on Monday morning - what path?

You are saying that someone says that 91 south is blocked? That is odd, since it is a major N/S Interstate. At any rate, if you can take 91 south, then 691 west when you come to it, it will drop you back on 84 after Hartford. We use that route, as even without traffic, 84 through Hartford is nice to avoid. I think the engineers had a rough night before the laid out that section.
