About the Project

This project will widen Stringfellow Road to four lanes, 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.

Stringfellow Road will be widened from two lanes to four lanes, separated by a 16-foot concrete median. 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 sees severe congestion in both directions during peak periods. This project will increase 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, starting at Route 50 and moving south. 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.

Northbound and southbound traffic on Stringfellow Road has been shifted onto the new detour road parallel to Stringfellow Road between Melville Lane and Point Pleasant Drive. Traffic will remain in this configuration for several months while crews construct the second section of the new bridge of Big Rocky Run and the ultimate Stringfellow Road southbound lanes. Drivers can expect delays and temporary stoppages along Stringfellow Road as contractor crews install new traffic signal poles.  Southbound Stringfellow Road traffic is expected to be switched onto the newly constructed, widened portion of Stringfellow Road between Fair Lakes Boulevard and Chantilly High School in July 2014. 

Pedestrian Impacts and Detours

The pedestrian trail between Stream Valley Drive and Poplar Tree Road on the northbound side of Stringfellow Road has been reopened. A temporary asphalt path has been installed on the northbound side of Stringfellow Road that will allow for continuous pedestrian access through the project limits.

In May 2014, construction crews began to install new storm drainage pipe along the Stringfellow Road northbound curbline between Point Pleasant Drive and Poplar Tree Road. Pedestrians on the existing sidewalk should be alert of construction activities. Onsite flaggers will be provided to guide pedestrians past the work area.

Reconstruction of the Greenbriar Park parking lot is expected to begin over the summer months. When construction begins, park users are encouraged to use the rear parking lot that can be accessed via Melville Lane.
