  • The center lane will be dedicated to through traffic only
  • The right lane will be dedicated to right turns only

This detour will affect CUE Bus riders who use the Green 1 Route — click here for information.

The detour has been monitored and staffed continuously since its implementation, and will continue to be as long as it is in effect. 

The city has posted signage on Chain Bridge Road and Fairfax Boulevard announcing this detour. Drivers are encouraged to subscribe to Fairfax City Alert to receive road construction alerts via text and email.

Additionally, notices have been posted on the city website, and on Cityscreen-12, the city television station. 

The Northfax project will provide road improvements and pedestrian accommodations, as well as eliminate roadway flooding, at the intersection of Route 123/Chain Bridge Road and Fairfax Boulevard. Construction will be completed in summer 2018. Information:, 703-385-7810.
