Traffic Changes at Route 123/I-66 Interchange Starting on or about November 30
Drivers from Route 123 (Chain Bridge Road) South will use temporary ramp and traffic signal to reach I-66 West

FAIRFAX – Drivers heading from Route 123 (Chain Bridge Road) South to I-66 West will use a new left-turn lane and traffic signal to reach a temporary access ramp to the interstate beginning during the daytime hours on or about Tuesday, November 30. This detour is anticipated to be in place through March 2022, while crews construct the new, permanent ramp from southbound Route 123 to I-66 West as part of reconstruction of the Route 123 Interchange for the Transform 66 Outside the Beltway Project.

Starting during the daytime hours of Tuesday, November 30, drivers should expect the following traffic pattern change, weather permitting:

Route 123 South to I-66 West

  • The current ramp from Route 123 South to I-66 West will close.
  • Drivers will be directed to continue south beyond the old access ramp and stay to the left. At the signalized intersection with the ramp from I-66 West, drivers will turn left from a dedicated left-turn lane to reach a newly constructed ramp that merges into the current ramp from Route 123 North to I-66 West (see graphic below).
  • There will be two travel lanes on Route 123 North and South through the interchange.
  • Drivers traveling from Route 123 North to I-66 West should stay alert for traffic merging onto the ramp from the left. Detoured drivers merging from the temporary ramp connection onto the ramp from Route 123 North will be required to yield to vehicles already on the ramp.

Lane closure details to implement the traffic pattern change include: 

Tuesday, November 30
I-66 West at Route 123

  • The right lane on I-66 West at Route 123 will be closed from 9 a.m. to 2 p.m.
  • All lanes will reopen by 2 p.m. 

Ramp from I-66 West to Route 123 South

  • One (left) lane on the ramp will be closed from 9 a.m. to 2 p.m.
  • All lanes will reopen by 2 p.m.

All work is weather dependent and will be rescheduled to Wednesday, December 1, if inclement conditions occur.

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 I-66 corridor trail and planned trails in the City of Fairfax. 

Drivers should always use caution and pay attention to lane markings and roadway signs in construction work zones.
