About the Study

This study is assessing an extension of Town Center Parkway below the Dulles Toll Road (Route 267), the Dulles International Airport Access Highway and the Metrorail Silver Line aimed at reducing congestion on adjacent roadways and improving accessibility and connectivity to Reston Town Center for drivers, bicyclists and pedestrians.

The project team is analyzing the extension, about a half-mile, from Town Center Parkway's current southern terminus at Sunset Hills Road to Sunrise Valley Drive via an underpass, with the new road aligning west of the CoreSite building on Sunrise Valley Drive.
