About the Project

Cedar Lane

On May 15, 2020, the Cedar Lane bridge over I-66 closed for about six months for reconstruction to accommodate the widening of I-66. Find information about construction, detours, and bus routes below. Watch a video overview hereSubmit questions, comments, and other feedback to the project team here.

The Cedar Lane bridge over I-66 is being rebuilt to accommodate the widening of I-66 and will include a shared-use path and wider sidewalk, as well as a nearby connection 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.

Planned Six-Month Closure of Cedar Lane Bridge

The Cedar Lane bridge closed on May 15, 2020, for demolition and reconstruction that will last until late November 2020. Closing the bridge for this period will reduce the duration and impacts of construction on travelers and surrounding neighborhoods to about six months, compared to a partial closure that would have taken more than two years to complete.

Benefits of this approach include:

  • Neighbors will experience fewer nights of noise from bridge demolition activities
  • Drivers on I-66 will have fewer months of extended lane shifts for bridge pier construction
  • The project team will maximize construction activity over Metrorail tracks during the planned Orange Line shutdown from Memorial Day to Labor Day

Ask questions or provide comments about construction plans by calling 703-662-3892, emailing, or submitting through the comment form.

The piers for the existing Cedar Lane bridge (shown in orange) must be demolished to make room for the wider I-66. The new bridge (shown in gray) is wider than the old bridge and will require just one pier.

Construction Update (Updated Sept. 25, 2020)

Recent Construction Progress:

  • Installation of bridge beams over I-66 East and West and the Metrorail Orange Line complete.
  • Installation of lagging for bridge deck underway. 

Upcoming Construction Activities:

  • Removal of shoring tower.
  • Construction of bridge superstructure.
  • Pour concrete bridge deck.

All beams are installed for the new Cedar Lane Bridge. Crews have begun installing overhang brackets and removing the shoring tower along I-66 East. (Sept. 25)

What Neighbors Can Expect

Some construction and demolition activities will generate noise or other impacts, and must occur during nighttime hours when multiple travel lanes on I-66 can be closed. When those activities occur, measures will be taken to minimize impacts as much as feasible, including:

  • Demolished concrete will be hauled during daytime hours when possible and will be processed off site
  • Work area lighting will be directed towards roadway/away from residences
  • Dust control measures will be in place
  • Construction vibration and noise will be monitored
  • Portions of the bridge not over I-66 and the Metrorail tracks will be demolished during daytime hours when possible

Project emails and this website will be used to communicate major traffic switches and nighttime work.

What Drivers Can Expect

The Cedar Lane bridge over I-66 closed for about six months on May 15, 2020. A posted detour routes drivers to Gallows Road to cross I-66 using either Cottage Street (north side of I-66) or Hilltop Road and Lee Highway (south side of I-66). 

Drivers on I-66 will encounter lane shifts, lane closures, and overnight stoppages to accommodate bridge construction activities. Sign up for project email updates to keep up to date.

Changes for Pedestrians, Cyclists, and Bus Passengers

During the Cedar Lane bridge closure, pedestrians and cyclists have a marked detour using existing sidewalks and shared-use path to cross I-66 near the Dunn Loring-Merrifield Metrorail Station. The detour uses sidewalks along Cottage Street on the north side of I-66, shared-use path along Gallows Road, and multiple sidewalks on the south side of I-66.

Expanded Service and Route Changes for Fairfax Connector Buses

Fairfax Connector Routes 467/462 use the Cedar Lane bridge to travel between the Dunn Loring-Merrifield Metrorail station and stops in Vienna and Tysons. These routes have been modified during the bridge closure and will provide additional service on weekdays and weekends. Service on these routes is FREE for the duration of the bridge closure. For schedule information, visit or call 703-339-7200, TTY 711 (Se habla Español).

Bicycle and Pedestrian Improvements with the New Bridge

The new bridge will include a shared-use path on the east side and a sidewalk on the west side. Just north of I-66, there will be a connection to the 10-foot-wide shared-use path that is being built parallel to I-66 from Dunn Loring to Centreville as part of the project. This paved trail will provide cyclists and pedestrians with off-road access to Metrorail stations, parks, neighborhoods, and other trails. Learn more here.
