About the Project

Stringfellow Road

Stringfellow Road

Stringfellow Road at I-66 will be modified to add full-time Express Lanes access to and from the east. These ramps will provide commuter buses, vanpools, and carpools with convenient access from the Stringfellow Road Park & Ride lot to the Vienna-Fairfax/GMU Metrorail Station, Tysons, Arlington, and Washington using the region’s express lanes network.

Stringfellow Road Express Lanes Access

  • The previous ramps are being replaced by new ramps that will provide Express Lanes access to and from the east.
  • No general-purpose lanes access is being added.

Stringfellow Road 66 EL Access

I-66 West Ramp to Stringfellow Road to Close for Express Lanes Construction On or About Thursday, November 10

Crews will close the ramp from I-66 West to Stringfellow Road during the evening hours Thursday, November 10, for continued construction related to the Transform 66 Outside the Beltway Project. The ramp will reopen later this year as a full-time, Express Lanes-only ramp. The ramp will no longer provide access from the I-66 general-purpose lanes to Stringfellow Road.

Details include:

Beginning on or about Thursday, November 10
Ramp from I-66 West to Stringfellow Road  

  • The ramp will close around 8 p.m.
  • The ramp will reopen as an Express Lanes-only ramp before the end of the year, as early as mid- to late-November, as part of opening the eastern segment of the 66 Express Lanes from Route 28 in Centreville to I-495 (Capital Beltway). 

The ramp from Stringfellow Road to I-66 East closed earlier this month.

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

Once the eastern section of 66 Express Lanes outside the Beltway opens, motorists can choose to use the lanes by paying a toll with an E-ZPass or by using one of the other payment options available through I-66 EMP such as paying online, via the mail, by calling 833-643-2867, or in person at the 66 Express Lanes Customer Service Center in Manassas. Payment options other than E-ZPass will incur administrative fees. More information can be found at Ride66Express.com.

Eligible High Occupancy Vehicles (HOVs) can travel the lanes for free with an E-ZPass Flex set to “carpool mode.” After this remaining section of 66 Express Lanes opens, vehicles will need to have three or more occupants to qualify as an HOV and travel the Express Lanes for free.

This change from HOV-2+ to HOV-3+ will apply across the entire I-66 corridor between Route 15 in Haymarket and Route 29 (Lee Highway) in Rosslyn - including I-66 Express Lanes located inside the Beltway, which operate on weekdays-only on westbound I-66 from 3-7 p.m. and on eastbound I-66 from 5:30-9:30 a.m.
