 Not sure about that, but it is quite slow headed southbound past Quantico. Northbound 95 at Centerport Parkway should be getting by the work zone single file to the right. And then at Quantico, or make that triangle on northbound 95, you get by single file to the left. Mr. Wash Car Wash now open in Tyson's. Watch your car today. Their lines go much faster than D.C. traffic. With 11 locations, a Mr. Wash is near you. Visit mrwash.com. Bob Himmler, WTOP Traffic.
