 The Constitution Avenue is open along the National Mall. 17th Street is closed north of it. 395, 695, and 295 getting heavier. No mishaps on those freeways. Outbound on New York Avenue, traffic jammed out of Ivy City. Near Bladensburg Road, it was, at last report, only one lane getting by an emergency work zone. Volume delays building on the Beltway. A slow afternoon, both loops near the American Legion Bridge.
