I asked this question in the "Mid Atlantic" forum but got no response so perhaps the traffic (pun intended) is heavier here.

We're driving roundtrip to Baltimore from NYC on Sunday. I think I can find construction alerts on the NJ Turnpike. But what about on I-95 in Maryland, Delaware and even up toward Philly (we'll be taking a cheesesteak break). Anyone know how I can find out if there are major plans for construction so I can plan alternate routes? Thanks.
