 Interloop traffic slow, leaving Tysons toward the American Legion Bridge. The work zone had the left lane blocked, and one on the outer loop near Georgetown Pike had the right lane. 395 southbound near Shirlington, the left lane was blocked. In the district, we have a different set of road closures for the NATO summit today. One of the unplanned, unpublicized routes is going to be Pennsylvania Avenue near Federal Triangle. That is apparently closed, along with a portion of Constitution Avenue just west of the capital.
