 Coming out of Alexandria, approaching the Woodrow Wilson Bridge. In southern Fairfax County, Lorton, the police investigation into a series of crashes on Route 1. Southbound traffic beyond Armistead Road sent onto the service road to get by. Northbound drivers should be getting by to the right, but delayed both ways on Route 1. Might as well take 95. Friday traffic is not bad at all. 95 volume delays are brief.
