 I-95, that's where the volume in, and it's off and on on the southbound side between Lorton and Dale City. Still not that bad in the northbound direction with some brief volume slowdowns leaving Thornburg, headed toward Route 17 in Fredericksburg. July 4th, door busters are here at Lowe's. Don't miss your chance for big savings on grills, outdoor string lights, and more. Shop the deals before they're gone, because Lowe's knows savings. Rick McClure, WTOP Traffic.
