Traffic pattern changes, overnight ramp closure at Route 123/I-66 Interchange starting February 21st

Drivers from I-66 East will use the new ramp and traffic signal to reach Route 123 North

Drivers exiting from I-66 East to Route 123 (Chain Bridge Road) North toward Oakton will use a new ramp and traffic signal beginning on or about Friday night, Feb. 21.

Traffic heading to Route 123 North will use the current exit from I-66 East to Route 123 South, then stay to the left to use two signal-controlled turn lanes to turn left onto northbound Route 123. Traffic on I-66 East heading to Route 123 South will stay to the right using the existing exit ramp.

Beginning on or about Feb. 21, drivers exiting I-66 East to Route 123 North will use a new exit ramp and two left-turn lanes at a temporary traffic signal.

Implementing the traffic shift will require lane closures and stoppages on Friday night, Feb. 21. A single lane on Route 123 North and South will be closed between 10 p.m. and 8 a.m. The ramp from I-66 East to Route 123 will be closed between midnight and 5 a.m. Traffic will be detoured farther east to Route 243 (Nutley Street) North, stay to the right for I-66 West, then follow signs to Route 123 North or South.

The old loop ramp from I-66 East to Route 123 North will be demolished to allow construction of Express Lanes ramps and a shared-use path at the redesigned Route 123 Interchange as part of the Transform 66 Outside the Beltway Project. Drivers should be alert for changing traffic patterns and the new traffic signal. Drivers are reminded to slow down and pay attention as construction-related detours and traffic pattern changes will continue through 2022 when the new Express Lanes open.
