About the Project

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 Ramps Now Open to Full-time, Two-way Traffic

The Stringfellow Road ramps to I-66 East and from I-66 West converted from alternating, one-way travel to full-time, two-way travel in October 2020. Drivers on Stringfellow Road traveling to I-66 East, and drivers on I-66 West traveling to Stringfellow Road are permitted to use the ramps 24 hours a day. HOV-2 restrictions will remain in effect during peak periods. 

Drivers should expect the following traffic pattern change, weather permitting:

  • The existing Stringfellow Road ramps to I-66 East and from I-66 West allow full-time, two-way travel as of October 2020. Two-way traffic on the ramp will be separated by flexible, plastic bollards.
  • HOV-2 restrictions will remain in place during peak periods. The ramp from Stringfellow Road to I-66 East will be restricted to HOV-2 Only on weekdays between 5:30 a.m. and 9: 30 a.m. The ramp from I-66 West to Stringfellow Road will be restricted to HOV-2 Only on weekdays between 3 p.m. and 7 p.m.
  • Only buses, two-axle, and emergency vehicles will be permitted to use the ramps. Trucks will not be allowed to use the ramps at this time.

Construction Update (Updated September 7, 2021)

Recent Construction Progress:

  • Water line, power line relocation along Stringfellow Road
  • Bridge beams placed for new I-66 West travel lanes

Upcoming Construction Activities:

  • Bridge deck complete along I-66 West
  • Shift I-66 travel lanes to allow room for Express Lanes construction

Piers and ramp for the future flyover ramp from the I-66 East Express Lanes to the I-66 East general purpose lanes and Fairfax County Parkway exit can be seen taking shape toward the top of the roadway. (August 24, 2021)
