I-66 Trail
A 16-mile extension of Virginia’s beloved Custis Trail
The Virginia Department of Transportation will add 16 miles of shared-use path adjacent to Interstate 66 as part of its Transform 66 Initiative. Some segments will be located along adjacent roads, and others will be located along the interstate corridor (inside and outside of the sound wall). These segments will be separated from the roadway by a concrete barrier and fence, but trail users still have concerns about air quality, noise, safety, and access.
