I-66 West Overnight Closures, Detour in Centreville Area Planned Jan. 27 – Feb. 1

About the Project

Gallows Road

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.

Traffic Shifted to New Gallows Road Bridge

The new Gallows Road Bridge over I-66 is being built in two phases so that it can remain open for vehicles and pedestrians during construction. The first portion of the new bridge is just to the east of the current bridge. Both northbound and southbound Gallows Road travel lanes shifted to the new bridge in October 2021. Two-way traffic with two lanes in each direction will run on the new Gallows Road North Bridge while the old bridge is demolished and the southbound portion of the bridge is constructed. The remainder of the bridge is estimated to be complete in summer 2022.

Pedestrian access shifted to the east side of the new bridge at the end of October 2021. Pedestrians will use the sidewalk on the east side of the new Gallows Road Bridge during demolition of the old bridge and construction of the new span over I-66. Pedestrian detours will cross Gallows Road using the crosswalks at Cottage Street and Avenir Place/Bellforest Drive. 

Access to the Dunn Loring Metrorail Station, Stenwood Elementary School, and other destinations will be maintained while the southbound bridge is being built.

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.

Demolition of the Old Gallows Road Bridge 

Demolition of the old Gallows Road Bridge involves breaking up the concrete deck using jackhammers, saw cutters, and hoe rams, followed by removal of the steel bridge beams and concrete piers and abutments.

To protect motorists and work crews, demolition work that occurs over I-66 travel lanes and the Dunn Loring Metrorail Station will be completed during the overnight hours (typically between 11 p.m. and 5 a.m.), when multiple lanes of I-66 can be closed and it is safe to work over the Metrorail station and tracks. Demolition work that does not occur over I-66 travel lanes will be completed during daytime hours, whenever possible. Approximately 30-40 nights of work is expected to tear down the old crossing, depending on weather and other factors, and is anticipated to continue through early 2022. 

“Pre-demolition activity” on the old bridge began in late October 2021 and occurred during daytime and overnight hours. This lighter activity included removing railing and fencing, demolishing parapet (wall) on the bridge, and constructing a platform under the old bridge to protect the WMATA facilities. These are “less noisy” activities than the bridge deck demolition that will follow.

Crews sawcut sections of the bridge deck above Metrorail facilities during daytime hours, which reduced the number of nights of demolition. This work completed on November 19, 2021.

With bridge deck demolition over the Dunn Loring Metrorail Station completed, crews will next demolish the northern portion of the old bridge, followed by the southern portion. The spans over I-66 East and West and the bridge piers can only be demolished during the overnight hours when multi-lane closures on I-66 are allowed. The spans farthest north and farthest south, and the old bridge abutments will be demolished during the daytime hours.

Drivers should expect nightly lane closures on I-66 East and West near Gallows Road as bridge demolition progresses. 

Overnight Demolition of the Old Gallows Road Bridge over I-66 Continues This Week, January 24-26

Overnight demolition of the old Gallows Road Bridge over I-66 is planned to continue this week, Monday, January 24, through Wednesday, January 26, with removal of the bridge piers along I-66 East.

What’s ahead for this weekend and next week: 

  • Crews will continue to demolish the old bridge piers along I-66 East using jack hammers, saw cutters, and hoe rams.
  • Demolition of the old piers must take place during the overnight hours when multiple lanes can be closed on I-66 to safely accommodate this work.  
  • Crews will also begin demolition the old bridge abutment and approaches on the south side of I-66 during the daytime hours. Work will require use of jack hammers, saw cutters, and hoe rams. No lane closures will be required for this work.
  • Construction of the new northern bridge abutment for the new Gallows Road South Bridge over I-66 will continue this weekend and next week with pile driving during the daytime hours.
  • Construction of the new center bridge pier along I-66 West will begin during the overnight hours next week, January 24-28, with drill shaft construction.
  • All work is weather dependent and schedules may shift if inclement conditions occur.

What Drivers Should Expect:

Monday, January 24, though Wednesday, January 26
I-66 East approaching Gallows Road

  • Three lanes will be closed from 10 p.m. to 5 a.m. nightly for bridge demolition.
  • Drivers should expect periodic stoppages of up to 20 minutes between 11 p.m. and 4 a.m. nightly.
  • All lanes will reopen by 5 a.m.

Demolition Progress to Date:

  • During the week of January 18, crews completed removal of the remaining beams from the old bridge and began demolition of the bridge piers along I-66 East.

What Neighbors Should Expect During Demolition

  • Demolition work will begin with removal of the concrete bridge deck using jackhammers, saw cutters, and hoe rams, followed by removal of steel bridge beams. 
  • Most of the bridge is directly over I-66 or the Dunn Loring Metrorail Station and will need to be demolished during overnight hours when multiple lanes can be closed on I-66 to safely accommodate this work.
  • Demolition activities will occur during daytime hours when feasible to minimize impacts to the nearby communities.  

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.

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 Metrorail 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.
