New Temporary Traffic Change At Route 123/I-66 Interchange Begins This Week
Ramp from I-66 West to Route 123 North to close for approximately three months; Drivers will use temporary traffic signals, new right-turn lanes to access Route 123 North

FAIRFAX - Drivers traveling on I-66 West to Route 123 (Chain Bridge Road) North toward Oakton will begin using a new, temporary exit ramp this week for approximately three months. The temporary ramp will have two right-turn lanes and a traffic signal to allow drivers to access Route 123 (Chain Bridge Road) North.  The change is scheduled to occur on August 14, weather permitting.

The old ramp from I-66 West to Route 123 North will be demolished to allow construction of a new ramp slightly to the east. This change is necessary to build dedicated Express Lanes ramps and a shared-use path at the Route 123 Interchange, as part of the Transform 66 Outside the Beltway Project.

During construction, posted travel speeds along Route 123 through the I-66 Interchange have been reduced to 35 mph, consistent with posted travel speeds on Route 123 north and south of I-66. Drivers traveling north on Route 123 should use caution and be alert for vehicles entering the roadway and the new traffic signal.

Drivers should expect construction-related detours and traffic pattern changes as work progresses at the Route 123/I-66 Interchange during the next three years of construction. Drivers are reminded to slow down and pay attention to lane markings and roadway signs at all times.

Learn more about the I-66 Outside the Beltway Project and sign up for project updates and lane closure alerts at Transform66.org.

Beginning on or about August 14, drivers exiting I-66 West to Route 123 (Chain Bridge Road) North will use a new exit ramp and turn right at a temporary traffic signal.
