Project Limits

Please note: The Fairfax County Parkway widening noise barrier survey results are available.

Popes Head Road Interchange

This project will replace the traffic signal at Fairfax County Parkway (Route 286) and Popes Head Road (Route 654) with an interchange that includes access to the future Shirley Gate Road extension and Patriot Park.

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

This project will widen about five miles of Fairfax County Parkway from four lanes to six between Route 29 (Lee Highway) and Route 123 (Ox Road).

The project also includes:

The project will be done in two phases: Phase 1 from Route 29 to Nomes Court, and Phase 2 from Nomes Court to Route 123.

Within the project limits, Fairfax County Parkway averages about 78,000 vehicles a day and Popes Head Road averages about 3,200.

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.


These projects will reduce congestion and improve safety and accessibility for drivers, bicyclists and pedestrians.
