 To Fredericksburg, the southbound pace is decent, a little sluggish in the Springfield Interchange and down at the Purple Heart Bridge. But in Stafford County, northbound on 95, near Route 630, exit 140, crash response blocks the left lane. That is northbound. In Maryland, on the interloop, residual delays through Landover, but the emergency road work cleared at Ritchie Marlboro Road, all lanes open.
