The speed limit on Richmond Highway (Route 1) has been permanently lowered through much of Fairfax County.
Starting next Tuesday (May 23), the legal limit will be reduced from 45 to 35 mph along a roughly 7-mile stretch between the Alexandria City limits at the Capital Beltway (I-495) and Jeff Todd Way/Mount Vernon Memorial Highway, the Virginia and Fairfax County transportation departments announced yesterday (Monday).
