 Northbound I-95 heavy on the brakes approaching the Prince William Parkway toward 123. Then in Lorton toward Newington where travel lanes reported to be open. Back in Maryland, westbound 50 near 450 in parole. That's where the right side is blocked for the police activity. Inbound River Road, two sections for the work zone. First, after Braeburn Parkway, the right lane gets by the work. Then near Goldsboro Road, the left lane gets by that particular work zone.
