 A little bit of congestion through the overnight work zone between Quantico and Dumfries. Left and center lanes are blocked. Traffic gets by single file to the right. A little bit busy as you get closer to 234, and then all of your lanes are open, and it's a lot better on the way up to Dale City and Springfield. Southbound on 395, a couple of slow spots. South of the Pentagon, you've got construction that blocks the left side of the roadway. Stay over to the far right.
