Traffic Advisory - Fairfax County

Fairfax County public safety agencies are working with our state and regional partners to monitor and prepare for potential traffic impacts in the county through the weekend. Please plan ahead as there is the potential for commercial and passenger vehicle convoys traveling in and around the National Capital Region.

For real-time traffic conditions and to view traffic cameras, the public is encouraged to visit the Virginia Department of Transportation’s (VDOT) 511 website at www.511virginia.org. On Twitter, follow @vadotnova for more information and @511statewideva for automated traffic incident updates.
