FAIRFAX – Drivers exiting from Route 123 (Chain Bridge Road) South to I-66 East will use new left turn lanes and a traffic signal to reach a new ramp beginning on or about March 21. 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.

Traffic change details include:

• The loop ramp from southbound Route 123 to I-66 East will close. Drivers on southbound Route 123 will access I-66 East using two traffic signal-controlled left-turn lanes to reach a new ramp, then merge onto the current ramp from Route 123 North to I-66 East (see graphic below)
• Two travel lanes will continue through the interchange in each direction
• Drivers traveling from northbound Route 123 to I-66 East should be alert for traffic merging onto the ramp from the left

The old loop ramp from Route 123 South to I-66 East will be demolished to allow construction of the redesigned interchange.

Construction-related detours and traffic pattern changes will continue through 2022 as crews rebuild the Route 123 Interchange to include Express Lanes access. Drivers are reminded to slow down and pay attention as construction-related detour and traffic pattern changes will continue through 2022 when the new Express Lanes open.

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