About the Project

Gallows Road

Gallows Road is being rebuilt where it crosses I-66. The new alignment will include improved bicycle and pedestrian facilities on the bridge over I-66 and access to the new shared-use path being built along I-66. The new design will:

  • Straighten Gallows Road to improve sightlines for travelers
  • Add bike lanes and wider sidewalks in each direction on the bridge over I-66
  • Leave room for future widening of Gallows Road to the north toward Tysons
  • Connect to the new shared-use path being built along I-66

Get a closer look at what’s planned through the Transform 66 Interactive Map.

New Gallows Road Bridge

The new Gallows Road Bridge will be wider and include a 5’ bike lane in each direction. Pedestrians will be able to use a 7’ wide sidewalk along northbound Gallows Road or a 10’ wide barrier-separated path along southbound Gallows Road. Improved pedestrian and bicycle facilities will tie into the Dunn Loring-Merrifield Metrorail Station.

Building the New Bridge

The new Gallows Road bridge will be built in two phases so that it can remain open for vehicles and pedestrians during construction. Four lanes and pedestrian access to the Dunn Loring Metro will be maintained during construction.

First, a new bridge will be built just to the east of the current bridge. When complete (estimated in mid-2021), northbound and southbound traffic will be shifted from the old bridge, which will then be demolished. A new bridge will be built in its place, which will carry southbound traffic and the shared-use path in the final configuration (estimated in early 2022). 

New Shared-Use Path

A 10-foot-wide shared-use path is being built parallel to I-66 from Dunn Loring to Centreville as part of the project, with its eastern terminus at Gallows Road. This paved trail will provide cyclists and pedestrians with off-road access to Metro stations, parks, other trails, and communities stretching from Dunn Loring to Centreville. Sidewalks and bike lanes along Gallows Road will connect the new path to the nearby W&OD Trail. Learn more here.

Construction Update (Updated May 25, 2021)

Bridge deck has been poured for the new Gallows Road bridge northbound span. Approaches are being constructed to tie-in the new bridge to the existing roadway. Progress on the retaining walls and noise walls to the east of Gallows Road is also visible. (May 2, 2021)

What Neighbors Can Expect

  • Noisy construction activities such as bridge demolition and pile driving will be avoided at night, when possible. Noise to expect at night includes back-up alarms on equipment and trucks, which is necessary to protect worker safety.
  • Lighting of the construction work area will be directed to minimize light pollution for nearby residents.
  • Pedestrian access over I-66 and to Dunn Loring-Merrifield Metrorail Station will be maintained on at least one side of Gallows Road during construction.
  • The project team has met regularly with Stenwood Elementary School administrators about minimizing construction impact on school activities.
  • Project emails and website will be used to communicate major traffic switches or nighttime work.

What Drivers Can Expect

  • Gallows Road will remain open during construction, but there will be long-term and short-term traffic shifts and other traffic pattern changes during construction.
  • Drivers should expect additional changes as work progresses at the interchange. Sign up for project email updates to keep up to date.
