FAIRFAX – Route 123 North will be shifted to a new bridge over I-66 during daytime hours on or about Wednesday, December 30. The southbound travel lanes of Route 123 will be shifted to the new bridge span several weeks later. The Route 123 bridges are being replaced as part of the Transform 66 Outside the Beltway Project.  

Access to and from I-66 at Route 123 will remain the same as it is currently.

Following this traffic shift, the current Route 123 North Bridge over I-66 will be demolished to allow for additional construction. Demolition of the current bridge is anticipated to begin on or about January 5. Most of the bridge is directly over I-66 and will need to be demolished during overnight hours, when multiple lanes can be closed on I-66 to safely accommodate this work. Demolition activities will occur during daytime hours when possible, to minimize impacts to nearby communities. Additional information and updates about demolition work and traffic closures will be provided on the project website. All work is weather dependent and schedules may shift if inclement conditions occur.

As construction continues through 2022 on the Route 123 and I-66 interchange, drivers should be alert for changing traffic patterns. Drivers are reminded to slow down and pay attention to lane markings and roadway signs at all times.

Beginning on or about December 30, the travel lanes of northbound Route 123 over I-66 will be shifted onto a new bridge.  The southbound Route 123 travel lanes will remain in their current alignment for several weeks. Access to/from I-66 East and West will remain the same.    

When complete, the reconstructed Route 123/I-66 Interchange will provide direct access to and from the new Express Lanes for both eastbound and westbound travelers. A new shared-use path through the interchange will provide connection between the new I-66 corridor trail and planned trails in the City of Fairfax. 

Weekly updates will be available at Transform66. org and on Twitter @VaDOTNOVA.
