 As you head from Arlington towards Roslyn, you need to stay to the left to get by there safely. On the northbound lanes of I-95, still busy through Dumfries with the construction taking away the right and center lanes. Southbound, they're also working in that same stretch. Right and center lanes, traffic only gets by single file to the left. A little more volume on the southbound side. It's kind of slow all the way down towards Quantico.
