About the Project

The Virginia Department of Transportation, in cooperation with the Federal Highway Administration (FHWA), is proposing to construct a limited-access roadway to the west of the Washington Dulles International Airport (IAD) in Loudoun County, Virginia. VDOT is conducting an environmental study to evaluate options for a proposed Dulles Air Cargo, Passenger, and Metro Access Highway (DACPMAH) that would extend from the interchange of the planned Northstar Boulevard/Bi-County Parkway (VA Route 411) and Lee-Jackson Memorial Highway (US Route 50) to a new entrance into the western portion of Dulles Airport.  

Presently, IAD is accessible from the west by way of US Route 50, Evergreen Mills Road (VA Route 621), Dulles Greenway (VA Route 267), and VA Route 606.  

The purpose of this project is to enhance the movement of people, passenger services and air cargo traffic to Washington Dulles International Airport and the planned Phase 2 extension of the Metrorail Silver Line. The proposed project is intended to reduce congestion and improve capacity on the existing roadway network in the Dulles South area.

The estimated study cost is approximately $1 million.
