Traffic alerts ►

The project will replace the current at-grade intersection on Route 15/17/29 at Business Route 15/17/29 with a grade-separated interchange. The interchange design will remove the existing traffic signal on Route 15/17/29, allowing free flow of through traffic. Motorists on Route 15/17/29 will use ramps to access Business Route 15/17/29 and Route 880 (Lord Fairfax Drive), which will cross Route 15/17/29 on a new overpass with roundabouts at each end. A park and ride facility will also be constructed southeast of the interchange.

Interchange is Partially Open to Traffic

(Click on the image above for a larger view of the interchange). NOTE: Ramp C will open to traffic on Aug. 25. The portion of Ramp D that does not connect to the roundabout and Spur F as labeled on the graphic above remain closed to traffic. 

The new Warrenton Southern Interchange will almost be in its final configuration when a new ramp opens on Aug. 25. Drivers are urged to follow signs and to use caution while traffic adjusts to the new pattern.

The ramp connecting from the roundabout on the west (Warrenton) side of the project to the acceleration ramp to southbound Route 15/17/29 toward Opal will open to traffic on Aug. 25, weather permitting. Motorists will also notice traffic pattern changes on Business Route 15/17/29.

The temporary detour via Route 643 (Meetze Road) will be removed.

Until the project is complete by Nov. 25, motorists are reminded to be alert for crews working near the travel lanes and to expect lane closures in both directions on Route 15/17/29 and flagging operations on Route 880 (Lord Fairfax Drive). The slip ramps near each roundabout will remain closed to traffic for construction vehicle access.

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.

Benefits 

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-separeted 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.
