3 April


Crews will begin installing concrete barriers, shifting lanes and setting up work zones on sections of I-66 Outside the Beltway, ramping up construction on the Transform I-66 initiative. This early work will allow heavier construction to begin on the new Express Lanes and other improvements that are being built along the 22.5-mile project corridor on I-66 between I-495 and Rt. 29/Gainesville.

In addition to roadway work, other early construction activities that will get underway this month include relocating utilities where necessary, grading and drainage work, installing erosion and sediment control measures such as construction fencing to protect the natural environment during construction, and removing trees where necessary.

Concrete barrier installation, lane shifts and work zone setup will occur in the following areas:

  • Eastbound I-66 at I-495/Capital Beltway
  • Both directions on I-66 between Chain Bridge Road (Route 123) and east of Waples Mill Road
  • Both directions on Route 28 north of I-66 between Westfields Boulevard and just north of Braddock and Walney Roads
  • Both directions on I-66 near Gainesville between Route 29 and west of Sudley Road
  • University Boulevard park and ride lot near Gainesville (east of Route 29 interchange)

Early construction activities began in December 2017 and will continue through early 2018. These early construction activities include geotechnical surveys and utility verification. FAM Construction is also conducting voluntary pre-construction condition surveys of properties located within approximately 100 feet of the project corridor.


Overnight lane closures will occur on Eastbound I-66 at I-495 for crews to shift travel lanes and set up work zones. Lanes will be shifted towards the outside shoulder to allow for work zones to be set up in the median. The lane shift is indefinite.

Between 9:00 p.m. until 9:00 a.m. on the nights of Friday, April 6, and Saturday, April 7**, drivers can expect to see the following traffic changes as Eastbound I-66 temporarily restricts to the single left travel lane:

  • Eastbound I-66 at Cedar Lane single lane closure starting at 9:00 p.m.
  • Eastbound I-66 at mile marker 64.2 double lane closure starting at 10:00 p.m.
  • Partial exit ramp closure from Northbound I-495 general purpose lanes and Northbound I-495 Express Lanes to Eastbound I-66 starting at 10:00 p.m.
  • Motorists should anticipate periodic rolling slowdowns of traffic exiting the Northbound I-495 Express Lanes to Eastbound I-66 during these hours.

Additionally, crews will begin removing the red colored road surface in the shoulder lane in both directions between Chain Bridge Road (Route 123) and US 50.  These shoulder use lanes will be converted to full-time travel lanes during peak periods throughout construction.

**All work is weather permitting.


Four travel lanes will remain open during peak periods throughout construction, with HOV-2 regulations on I-66 remaining in effect on weekdays from 5:30-9:30 a.m. in the eastbound direction and 3-7 p.m. in the westbound direction. Lane closures will occur during mid-day periods on weekdays, as well as during weekends and overnight hours.

Drivers are advised that as construction ramps up and lane shifts are implemented on I-66, the “red X” signs in use between Route 50 and I-495, which were part of VDOT’s Active Traffic Management (ATM) system, will be taken out of service.


Following the Design Public Hearings in November 2017, the project design is advancing to final stages. The final design noise analysis is underway with an expected completion date in late spring 2018. The results of the final design noise analysis will determine the height and placement of all noise walls along the corridor.

The Transform 66 Outside the Beltway project will upgrade 22.5 miles of Northern Virginia’s Interstate 66 between I-495/Capital Beltway and U.S. 29 in Gainesville into a multimodal corridor that moves more people, provides reliable trips and offers new travel options.   The $2.3 billion design-build project, which is scheduled for completion in December 2022, will result in two new Express Lanes alongside three general purpose lanes in each direction, auxiliary lanes where necessary, major interchange improvements, and new and expanded park and ride lots with more than 4,000 new spaces.  The Project includes 11 miles of new shared use trail along I-66 that integrate with County and Park trails, and 11 bridges with new or expanded additional bicycle and pedestrian facilities. The project will also preserve the median for future mass transit expansion.
