 Once you leave Falmouth area, you'll find it backed up a bit just before the Occoquan. After the bridge, you're all clear to the Springfield Interchange. Over on the southbound side near Lorton, crash activity kind of contained now to the left shoulder. It's crowding the left lane, so use a bit of caution. It's still going to be slow on that southbound side through Triangle down through Stafford County. South of Stafford County, you're clear down to the Fredericksburg area.
