Please note: The Fairfax County Parkway widening noise barrier survey results are now available.
Popes Head Road Interchange
Plans to replace the traffic signal at Fairfax County Parkway (Route 286) and Popes Head Road (Route 654) with an interchange, including access to the future Shirley Gate Road extension and Patriot Park, are being further developed and refined.
The preferred design option for the Popes Head Road interchange is Triple Roundabouts that will allow traffic to flow freely via two new bridges over Fairfax County Parkway.
Fairfax County Parkway Widening
Plans to widen about five miles of Fairfax County Parkway from four lanes to six between Route 29 (Lee Highway) and Route 123 (Ox Road) are being further developed and refined.
The widening will also include:
- Improving the Route 123 interchange and the Fairfax County Parkway/Burke Centre Parkway intersection.
- Providing a continuous shared-use path within the project limits by constructing the missing segment from Burke Centre Parkway to Route 123.
Within the project limits, Fairfax County Parkway averages up to 85,000 vehicles a day and Popes Head Road averages up to 4,000.
Estimated Costs
Preliminary Engineering: $17.7 million
Right of Way Acquisition and Utility Relocation: $19.4 million
Construction of Popes Head Road Interchange: $73.4 million
Construction of Fairfax County Parkway Widening: $182.2 million
Total: $292.7 million
These project costs are estimates and subject to change as the project design is further developed. The Popes Head Road interchange is fully funded and the Fairfax County Parkway widening is partially funded, with additional funding sources being evaluated as they become available. This project is financed with federal, state and local funds, including Smart Scale and Northern Virginia Transportation Authority funding.
Benefits
These projects aim to reduce congestion and improve safety and accessibility for drivers, bicyclists and pedestrians.
