The Loudoun County Parkway is a secondary state highway in eastern Loudoun County, Virginia. Two sections of the route currently exist, a southern portion signed as State Route 606 from Braddock Road north to Arcola Road which continues east as Old Ox Road, and a northern portion in Ashburn signed as three different numbers: State Route 772 between Ryan Road and Old Ryan Road, State Route 1950 between Old Ryan Road (now Mooreview Parkway) and Smith Switch Road, and State Route 607 from the intersection of Smith Switch Road to State Route 7.
Except for two small portions around Redskins Park and between Evergreen Mills Road and Arcola Road, the parkway is either four or six lanes.
South Riding and Arcola
Loudoun County Parkway begins at Braddock Road in South Riding and continues north across U.S. Route 50. The parkway continues north along the western boundary of Washington Dulles International Airport to the intersection of Arcola Road, where it becomes Old Ox Road and continues east toward Herndon. The parkway is planned to head north from there to connect to Ryan Road in Brambleton. This entire section of Loudoun County Parkway was originally Old Ox Road.
Brambleton and Ashburn
Loudoun County Parkway resumes at the intersection of Evergreen Ridge Drive south of Ryan Road a few miles south of the Dulles Greenway. The parkway heads north over the Greenway, and past the Verizon campus. After crossing Waxpool Road, the parkway continues north through corporate centers and Redskins Park. This section was once called Panorama Parkway. Until 2006, the section from Smith Switch Road to State Route 7 was an unpaved dirt road, but was rebuilt in 2006 as a four-lane divided highway as part of the Route 28 Improvement Project. As of 2012, Smith Switch Road no longer intersects directly with Loudoun County Parkway; instead it runs into the extension eastward of Gloucester Parkway that intersects Loudoun County Parkway.
