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.
