About the Project

This project has widened Stringfellow Road from two lanes to four, separated by a 16-foot concrete median, between Fair Lakes Boulevard and Route 50.

The first phase of the project began in October 2010 and focused on moving major utilities. VDOT completed all utility relocations in the spring of 2013.

The project also includes:  

  • a five- to six-foot-wide sidewalk on the west side of Stringfellow Road and a 10-foot wide path on the east side
  • wide curb lanes to accommodate bicyclists
  • a new bridge over Rocky Run
  • drainage improvements
  • landscaping
  • adding a left-turn lane northbound to Route 50, and
  • modifying the southbound approach to Route 50 to improve traffic flow.

This section of Stringfellow Road connects two major roads, Route 50 and Route 29, and had seen severe congestion in both directions during peak periods. This project has increased capacity on this section of road needed due to extensive growth in the corridor and resulting increases in traffic.

Stringfellow Road carries about 23,000 vehicles per day, and is expected to increase to 33,000 in 2034.

Traffic Impacts

During construction motorists can expect one of two lanes to be closed overnight as follows:

  • 9 p.m. to 5 a.m., Monday through Thursday nights
  • 10 p.m. to 9 a.m., Fridays and Saturdays
  • 10 p.m. to 5 a.m., Sunday nights

Drivers can also expect occasional daytime lane closures.

Drivers should expect alternating one-way traffic and temporary stoppages along Stringfellow Road. Drivers are asked to be aware of new traffic patterns after each closure as traffic is shifted away from the active construction areas.

Construction activities requiring temporary lane closures will be performed at night and drivers should expect alternating one-way traffic and temporary stoppages. However, due to noise concerns in areas of work that are adjacent to residential neighborhoods, daytime lane closures can also be expected. Variable message boards along Stringfellow Road will be illuminated and will provide advanced notification of anticipated impacts to traffic.

Drivers should expect additional delays throughout the corridor during the morning and afternoon rush hours.  The speed limit through the school zones at Chantilly High School and Rocky Run Middle School will be reduced to 25 MPH during these hours.

During reconstruction of the Greenbriar Park parking lots, park users are encouraged to use the rear parking lot that can be accessed via Melville Lane.

Pedestrian Impacts and Detours

Sidewalks have been installed along the west side of Stringfellow Road and allow for continuous pedestrian access through the project limits. Crosswalks have also been installed at project intersections. Pedestrians using these facilities should remain alert during construction activities. Construction of the sidewalks/trail on the east side of Stringfellow Road is underway and pedestrian detours are in place as needed.
