 On this Friday before Independence Day, westbound traffic is sluggish from Cox Creek onto the westbound bridge span. Baltimore-Washington Parkway southbound between 198 and 197, down to one lane at an incident. 95 will serve you better. Northbound traffic heavy through Laurel on both the parkway and the interstate. 270 uneventful. 15 crowded for a Friday in northern Loudoun County toward the Point of Rocks Bridge.
