Northern Virginia officials are calling for the delay of a massive military realignment to Fort Belvoir in order to prepare the area’s transportation networks for thousands of new commuters on southern Fairfax County roads.

With 22,000 military and civilian contractor jobs headed to Fort Belvoir, local policymakers say they want to see the Army postpone the strict 2011 deadline, at least for sending 18,000 of the workers to the Engineer Proving Ground. They include U.S. Reps. Jim Moran andTom Davis, as well as Fairfax County Supervisors Dana Kauffman and Gerald Hyland, who represent the two districts most affected by the move mandated under last year’s Base Realignment and Closure directives.
