As of Oct. 26, all ramps are open to traffic and the shared use path from Travelers Way to the Alwington Farm property is open for bicyclists and pedestrians. The new park and ride lot on Lord Fairfax Drive with 20 parking spaces is also available to commuters.

Under a $19.6 million contract, design-build contractor Shirley Contracting Company, LLC of Lorton, with design services from Dewberry of Fairfax, has worked since February 2018 to design and construct a grade-separated interchange to replace the signalized intersection of Route 15/17/29, Business Route 15/17/29 and Route 880 (Lord Fairfax Drive).

Initial construction activities began in early March 2019. On June 23, 2020, the new interchange partially opened to traffic and the traffic signal was removed.

Roundabout Driving Tips  

Drivers can follow these tips for navigating the roundabouts: 

  • Follow signs and pavement markings for your safety.
  • Slow down when approaching the roundabout and yield to traffic already in the roundabout.
  • As you enter the roundabout, keep right and drive in the counter-clockwise direction.
  • Do not turn left when entering a roundabout.
  • Use a turn signal and exit the roundabout with caution.

To learn more about roundabouts, visit VDOT's Innovative Intersections and Interchanges webpage.


The purpose of this project is to replace the existing at-grade intersection of Route 15/17/29, Route 15/17/29 Business and Route 880 (Lord Fairfax Road) with a grade-separated interchange to improve safety and capacity. Traffic conditions at this location include a high volume of northbound left turns into the town of Warrenton, a large (12 percent) volume of truck traffic, and local traffic associated with Lord Fairfax Community College, the Fauquier County landfill and homes nearby.
