FAIRFAX – Route 123 (Chain Bridge Road) South will be shifted temporarily to the new bridge over I-66 during daytime hours on or about Thursday, January 21. 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 in its current configuration.

Following this traffic pattern change, the current Route 123 South bridge over I-66 will be demolished to allow for construction of new ramps to I-66 general purpose and Express Lanes and shared-use path.

Demolition of the old northbound Route 123 bridge began earlier this month. Most of the demolition will need to occur 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 Jan. 21, the travel lanes of southbound Route 123 over I-66 will be shifted on to the new Route 123 Bridge. 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 66 Parallel Trail and planned trails in the City of Fairfax.
