Sidewalk Closure along Wiehle Avenue (West Side, between Sunset Hills Road and Reston Fire Station) 

• The existing sidewalk along the west side of Wiehle Avenue will be closed July 24.  
  • Signs will be installed in advance to direct the pedestrian/bicycle traffic to use the existing crosswalk south of the Sunset Hills Road/Wiehle Avenue intersection and the crosswalk at the Roger Bacon Drive/Isaac Newton Square South intersection.

(Update April 13, 2024) The pedestrian bridge over Wiehle Avenue at the W&OD trail is now in place. This bridge weighs 50 tons, is 147 feet long and 16 feet wide with steel trusses and sits approximately 18 feet above Wiehle Avenue. We expect the bridge to be open for use in mid-June. 

60% Completion - Spring 2024

(Update April 2, 2024) The construction of Wiehle Avenue at W&OD is approximately 60% completed and on schedule to be finished by early summer of 2024. The pedestrian bridge overpass will be erected on Saturday, April 13, 2024, in the early morning. 

Bridge Assembly: 
Prior to the erection, the bridge will be delivered in several sections, and assembled onsite, in the parking lot along the north side of the existing business facilities. The assembly work will start on April 2, 2024. This work does not require any pedestrian and/or vehicle detour. Traffic in the parking lot will be managed by delineating the work area by cones as well as by flaggers if two lanes of traffic cannot be maintained in the parking lot. 

40% Completion - Winter 2023

(Update December 2023) The Wiehle Avenue at W&OD Trail construction is 40% complete and on schedule for project completion in July 2024.

Groundbreaking - March 9, 2023

(Update March 14, 2023) The Wiehle Avenue at W&OD Trail is now in the construction phase and is expected to be completed by early Summer of 2024. The contract for the trail improvements was awarded to Allan Myers VA, Incorporated. Additionally, the adjacent properties were notified of the upcoming trail construction. A groundbreaking ceremony was held on March 9, 2023. 

A transportation management plan will be implemented to maintain uninterrupted pedestrian, bike and vehicular traffic during the construction. The plan includes the following:

• The gravel trail closure from the eastbound gravel trail entrance at 11480 Sunset Hill Road (west of Isaac Newton Square West) to Wiehle Avenue and from Michael Faraday Court to Wiehle Avenue.
• The existing asphalt trail to remain open except during nighttime hours (9 p.m. to 5 a.m. on any given day of the week) when the park is closed. 
• A 6’ safety fence will be installed along the asphalt trail to separate the construction area from the existing asphalt trail.
• The asphalt trail users will be detoured to use the newly constructed pedestrian bridge during the road improvements and trail/sidewalk construction along Wiehle Avenue. 
  • The work will be performed on one side of Wiehle Avenue at a time. 
  • Appropriate detour signs will be installed to direct pedestrian/bicycle traffic to the new pedestrian bridge to continue with their travel on W&OD asphalt trail. 
  • Appropriate traffic control signs will be installed for the closure of the sidewalk along Wiehle Avenue. Signs will be installed in advance of the closure to direct the pedestrian/bicycle traffic to use the existing crosswalk south of the Sunset Hills Road/Wiehle Avenue intersection and the crosswalk at the Roger Bacon Drive/Isaac Newton Square South intersection. 
• Every effort will be made to keep the Wiehle Avenue travel lanes open for continuous traffic flow. Please note that:
  • Single lane closure is allowed, when needed, during the construction. 
  • Total closure of Wiehle Avenue is only allowed during the pedestrian bridge installation. It is only allowed during overnight hours and will not exceed 15 minutes.
• Appropriate traffic controls will be installed for any sidewalk/trail, lane and road closure. 

Utility Relocation - Spring 2022

(Updated May 10, 2022) The relocation of utilities for Wiehle Avenue at W&OD trail project is moving forward as planned. Dominion Energy Virginia (DEV) completed the relocation of their overhead transmission facilities in August 2021. Adjustment of other utility facilities is necessary to accommodate the proposed trail improvements and pedestrian bridge construction over Wiehle Avenue. The relocation of AT&T's line, one of the nine utility facilities to be relocated, was completed on March 21. The relocation date(s) of the remaining utilities will start May 16, 2022. 

Throughout the relocation of utility facilities for the trail project, the W&OD Trail will be relocated, and pedestrians will need to use the adjacent paved or gravel trails. The W&OD Trail, within the limits of relocation area, will be detoured during this work. Work areas include the following:

• The paved trail from Wiehle Avenue to Isaac Newton Square West.    
• The gravel trail from Wiehle Avenue to Isaac Newton Square West.
• Approximately 200’ of the paved and gravel trail east of Wiehle Avenue.
• The sidewalk along Wiehle Avenue from Sunset Hills Road/Wiehle Avenue intersection to Roger Bacon Drive/Isaac Newton Square South intersection.

To maintain an uninterrupted pedestrian and bike traffic during the utility relocation:

• Trail users will be detoured to the adjacent gravel or paved trail during the utility relocation activity. 
• Appropriate traffic control signs will be installed for the closure of sidewalk along Wiehle Avenue. 
  • Signs will be installed in advance of the closure to direct the pedestrian and bike traffic to use the existing crosswalk at south of Sunset Hills Rd, the crosswalk at Sunset Hills Road/Wiehle Avenue intersection and the crosswalk at Roger Bacon Drive/Isaac Newton Square South intersection. 

For more information, please contact Sonia Shahnaj, Project Manager, Fairfax County Department of Transportation, by email at Sonia.Shahnaj@fairfaxcounty.gov or by calling 703-877-5600.

The relocation of utilities is expected to be completed by July 2022. The construction of the trail project is scheduled to begin in Fall 2022.
