 Meanwhile, on I-95 southbound, some slowing in Woodbridge and northbound through Quantico. Had one broken down in a lane before exit 148. And on the Beltway, outer loop, slow traffic leaving Tysons and approaching the Springfield Interchange. There is an accident on the ramp lanes to 95 and 644. Merging onto 95 south through Springfield, you get by single file to the left.
