In Design: Fairfax County Parkway Widening South

This project will widen about two miles of Fairfax County Parkway (Route 286) from four lanes to six between Route 123 (Ox Road) and Nomes Court. 

The project also includes:

• Installing concrete median barriers along tight curves and raised grass medians elsewhere 
• Constructing the missing shared-use path segment along Fairfax County Parkway between Route 123 and Burke Centre Parkway
• Making Fairfax County Parkway/Burke Centre Parkway intersection improvements including a new westbound Burke Centre Parkway free-flow right-turn lane 
• Adding a grade-separated bicyclist and pedestrian crossing just north of Burke Centre Parkway
• Improving the Route 123 interchange by widening the southbound Fairfax County Parkway ramp to Route 123 from one lane to two and adding a third left-turn lane on the ramp 
• Enhancing the sound wall along southbound Fairfax County Parkway between Clara Barton Drive and Route 123

Fairfax County Parkway averages about 61,000 vehicles a day within the project limits.
