About the Study

This study will assess traffic operations and safety and develop mitigation measures for the Route 28 corridor in the vicinity of the Dulles Toll Road/Dulles Greenway interchange (the "Project"), from Route 665 (Frying Pan Road) in Fairfax County to Route 846 (Sterling Boulevard) in Loudoun County. The study will identify safety and operational improvements, both short- and long-term, recognizing the complexity of this area, the multimodal nature of the corridors, the closely spaced interchanges, and the mutual interests of all parties to improve travel through this area in a safe and efficient manner. 

The study is being conducted with technical and financial participation from Fairfax County, Loudoun County, the Metropolitan Washington Airports Authority (MWAA) and Toll Road Investors Partnership II (TRIP II).

At the interchange, Route 28 averages 155,000 vehicles a day, the Dulles Toll Road averages 83,000 and the Dulles Greenway averages 46,000.
