FAIRFAX – Nightly lane closures will reduce southbound I-495 approaching I-66 to two travel lanes with multiple 20-minute traffic stoppages planned Tuesday, September 7, through Friday, September 10, as bridge beam installation continues at the interchange. The ramps from I-495 South to I-66 West, and from I-66 West to I-495 South will also need to be closed in conjunction with this work, which is part of the Transform 66 Outside the Beltway Project.

Drivers traveling on I-66 and I-495 during this time should expect delays and should consider using alternate routes. 

Details include:

Tuesday, September 7, through Friday, September 10
I-495 South approaching I-66

• Two lanes will be closed from 10 p.m. to 5 a.m. nightly.
• Drivers should expect periodic stoppages of up to 20 minutes during the overnight hours.
• All lanes will reopen by 5 a.m.

Ramp from I-495 South to I-66 West

• Beginning around 9 p.m. nightly, one of two lanes on the ramp will be closed.
• Between 11 p.m. and 4 a.m. nightly, there will be a full closure of the ramp.
• Traffic will be detoured farther south to the exit to Route 50 (Arlington Boulevard) East, stay to the right to Fairview Park, take the left fork to Fairview Park North, bear left at the traffic signal and stay to the right following signs to I-495 North and I-66, then follow signs to I-66 West.

All work is weather dependent and will be rescheduled if inclement conditions occur.

The I-66/I-495 Interchange is being modified with several new ramps and connections as part of the Transform 66 Outside the Beltway Project. Improvements at the interchange include adding access to and from the existing 495 Express Lanes and the new I-66 Express Lanes, as well as building new connections between express and general purpose lanes.
