The Virginia Department of Transportation (VDOT) and its private partner, I-66 Express Mobility Partners (I-66 EMP), are working closely with Fairfax and Prince William counties, bike advocacy groups, homeowners associations and local residents to advance the design of planned trail facilities as part of the overall Transform 66 Outside the Beltway Project. In addition to providing trails and connections on reconstructed roadways that cross I-66, a high-value trail is being developed in the physically-constrained I-66 corridor.
VDOT developed the concept plan for the I-66 Trail consistent with local jurisdiction trail plans. During earlier public outreach for the project, VDOT received many comments opposed to placing the trail on the residential side of noise barriers in locations where the trail passes near homes. Those comments led to a contract requirement to locate the trail on the highway side of noise barriers in areas adjacent to homes.

Conceptual Trail Plan:
In coordination with Prince William County, a future trail to be constructed by others has been proposed on parallel roadways. Two segments of this trail adjacent to proposed Park and Ride lots at University Blvd and along Balls Ford Road will be constructed as part of the Transform 66 project.
Between Route 29 in Centreville and Gallows Road, the current concept plans show approximately three miles of trail adjacent to the interstate and approximately eight miles of trail behind the noise barrier and with no noise barrier.
The bike trail will be 10 feet wide, with a 2 foot-wide shoulder on each side, in accordance with VDOT standards. In certain space-constrained locations, the trail width may be reduced to 8 feet, with shoulders.
Access to the trail will be provided about every half-mile. The 66 project team is working with Fairfax and Prince William counties as well, to identify the best location of each access point. Preliminary access points for the trail between Route 29 and Gallows Road are shown by green arrows in the Conceptual Trail Plan (see above map).
New bridges over I-66 will better accommodate cyclists and pedestrians, while connecting existing and planned bike routes. Two sample cross sections are shown here.

Working with the public and key stakeholders, our goal is to create a trail environment that invites cyclist and pedestrian usage and contributes to the “move-more-people-not-more-cars” mission of the Transform 66 project. Trail design features including the trail alignment and connections along the corridor were included in the overall project design plans at public hearings held in November 2017.
