 WTOP's Traffic and Weather Together. Let's go to Dave Dilline in the traffic center. Tough going on the beltway between Tysons and Bethesda. Interloop heavy and slow out of McLean across the Legion Bridge and lining up to take the 270 spur. On the spur, long-standing truck crash cleanup continues. Tractor trailer went over the guardrail into the woods early this morning. The right lane blocked into the middle of this afternoon on the spur near Democracy.
