Traffic Changes at Route 123/I-66 Interchange Starting on or about Feb. 21
Drivers from I-66 East will use new ramp and traffic signal to reach Route 123 North

FAIRFAX – 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.

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.

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.

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