Weekend Road and Rail: I-66 and Route 7 changes, bridge work and resurfacing abound

Work zones on Interstate 66 and Route 7 will begin to see some payoffs this weekend. In Maryland, it’s more resurfacing and Purple Line work. The District is addressing some much needed bridge work. Metro will have two shutdowns this weekend.

Here’s what you need to know if you’re hitting the roads in the D.C. area this weekend.



There are a few things to look for this weekend as part of the Transforms 66 Outside the Beltway Project, but we’re going to start with a change to the ongoing Route 7/Battlefield Parkway interchange renovations. A section of Battlefield Parkway has been closed since last July.

This weekend’s work is in reference to a few work zones that will be in place for finishing touches and a scheduled reopening for Monday.

The Battlefield Parkway will be reopening to traffic between Russell Branch Parkway and the Marketplace at the Potomac Station shopping center entrance after an 11-month closure. Drivers are asked to be alert for nightly lane closures and new travel patterns this weekend.

There will be night closures along Route 7 to implement the upcoming changes. This work will take the traffic signal of Route 7 and Cardinal Park Drive out of service permanently.

The nightly lane closures this weekend to implement these changes can be expected as scheduled, per the Virginia Department of Transportation (VDOT):

  • 9 p.m. through 9 a.m. Saturday: up to two lanes closed
  • 9 p.m. through 8 a.m. Sunday: up to two lanes closed
  • 8 p.m. to 5 a.m. through Monday: up to two eastbound lanes closed
  • Through 6 a.m. Monday: up to two westbound lanes closed

During this work time, the posted speed limit along Route 7 between the Leesburg Bypass and River Creek Parkway has been reduced to 45 mph. Drivers are asked to use caution while traveling through any work zone.

With the traffic signal at Route 7 and Cardinal Park Drive being taken out of service and removed on Monday, the intersection will permanently become a “right-in/right-out configuration.” This means that drivers heading to Cardinal Park Drive should make access from eastbound Route 7, and drivers on Cardinal Park Drive must turn right onto eastbound Route 7. When accessing Cardinal Park Drive from westbound Route 7, drivers should use Battlefield Parkway and Trailview Boulevard.

Big changes are also taking place with the I-66 Transformation Project this weekend as the new bridge on Route 50 West over I-66 is scheduled to open Sunday.

There will be overnight work through the week in preparation for this shift and opening. After the opening and shift of westbound 50, the demolition of the current bridge will commence.

This change will be the first of two coming to the Route 50/I-66 interchange. On Route 50 heading westbound over I-66, during the overnight hours Saturday, traffic will be shifted to the near-permanent bridge, which is aligned slightly to the east of the existing bridge. The eastbound lanes will be shifting to a new bridge in the coming weeks. After this Saturday’s traffic shift, the bridge demolition and new ramp construction will begin prompting daytime closures when possible, and any work over I-66 continuing to have closures during the overnights.

Starting at around 11 p.m. Friday, the ramp from westbound Route 50 to I-66 West will be closed and detoured.

There will also be a multi-day ramp closure for Route 50 West to the Fair Oaks Mall associated with this work. Some time near 10 p.m. on Saturday, crews will close this ramp and detour drivers toward West Ox Road for the U-turn back to Route 50 East and a choice of two entrances into the Fair Oaks Mall from that side. This ramp will be closed through 5 a.m. Tuesday morning.

There will be other I-66 Transformation projects running into the weekend, as per usual, so be sure to stay tuned to the WTOP Traffic Center for the latest impacts. Here are a few things to watch out for that have been continuing this week:

  • Overnight hours on I-66 West approaching I-495, I-66 will continually be closed for overhead bridge beam installation through Saturday morning.
  • Route 286 Fairfax County Parkway approaching I-66 will be reduced to a single travel lane with stoppages of up to 20 minutes overnights into Saturday morning.
  • Route 28 is reduced to a single travel lane with stoppages of up to 20 minutes for overhead gantry removal overnights through this weekend.
  • Overnight ramp closures continue at I-66 interchanges of I-495, Nutley Street, Routes 123, 50, 28, 29, 234 Business Sudley Road, and 234 Bypass Prince William Parkway.

Also opening Sunday, the new ramps connecting Braddock Road, Walney Road, Route 28, and I-66 West. Traffic changes at the Braddock Road/Walney Road Bridge over Route 28 include:

  • Activating two new traffic signals on the overpass.
  • Opening a new permanent ramp to I-66 West from Braddock Road and Walney Road.
  • From Walney Road, motorists will be able to turn left to Route 28 South and I-66 East using the current ramp from Braddock Road.
  • Due to the continued closure of the loop ramp from Route 28 South to I-66 East (through October 2021), vehicles heading to I-66 East will be detoured via the ramps at the Route 28/Route 29 (Lee Highway) Interchange.
  • Vehicles will not yet be able to cross the bridge headed east from Braddock Road to Walney Road. This movement is planned to open August 22, 2021.

All work is weather dependent.
