Full Overnight I-66 West Closures Planned At Beltway Interchange

FAIRFAX COUNTY, VA — Work at the Interstate 66 and Capital Beltway interchange will require a full I-66 closure in the westbound direction over several upcoming days.

The Virginia Department of Transportation said westbound I-66 will be closed at I-495 nightly from Tuesday, June 15 to Saturday, June 19. Closure hours are 11 p.m. to 5 a.m. nightly and until 6 a.m. on Saturday and Sunday.

Westbound I-66 traffic will be directed to exit at I-495 South, exit at Route 50 (Arlington Boulevard) east, stay to the right toward Fairview Park, take the left fork for Fairview Park North, bear left at the traffic signal, stay to the right following signs to I-495 North and I-66, and follow signs to I-66 West. The ramp from westbound I-66 to I-495 South and the 495 Express Lanes South will remain open to traffic.

The ramp from I-495 north to westbound I-66 will be reduced to a single lane nightly Tuesday to Thursday from 9:30 p.m. to 5 a.m., then Friday and Saturday from 10 p.m. to 8 a.m.

Work is weather dependent and will be rescheduled in the case of inclement weather.

Work at the I-66 and Beltway interchange is part of the Transform 66 Outside the Beltway Project. VDOT is 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 Lanes and general purpose lanes. The I-66 Express Lanes between the Beltway and University Boulevard in Gainesville are expected to open alongside regular lanes in December 2022.

Drivers should also be aware of upcoming overnight lane closures and traffic stoppages on I-66 from Nutley Street to Vaden Drive. On Friday, June 11, Saturday, June 12 and Monday, June 14, westbound I-66 will be reduced to one lane from 10 p.m. to 6 p.m. nightly (until 5 a.m. on Tuesday). Periodic stoppages up to 20 minutes will be in place each night.
