 Seeing extremely heavy volume on northbound Route 13. It's backing up at Harris Corner into Wilmington Manor and then Minkwoodale. Route 4 is also jammed solid into Newport. Not helping matters is Route 4 is a construction zone between Stanton and Newport with just one lane in each direction. So not a lot of viable alternatives. I am starting to see more volume on northbound 141 backing up at Lancaster Pike as well.
