 Jefferson County Sheriff's Office does confirm they are working an accident on the Shenandoah River Bridge. Traffic was stopped for a time both ways on the John Hall Bridge. Long backups have resulted on Route 340. That's all we know right now. In Maryland, fairly quiet on 270 and 95 as volume fills in here and there. BW Parkway southbound still down to one lane between 175 and Route 32. No travel trouble on Route 50 between the Beltway and the Bay Bridge.
