 Should be volume only in all cases. The E-ZPass needs to north out of Fredericksburg on your way toward the 14th Street Bridge and into the district. Elsewhere in Virginia, Fairfax, Route 29, your crash reported northbound as you approach Shirleygate and Waples Mill. Expect to find units and police on the scene. They may have at least stopped traffic at some points both ways there to deal with this wreck.
