Braddock Road in
South Riding. It then has an intersection with Tall Cedars Parkway. Then, Riding Center Drive, which takes you to
Freedom High School. The road then continues north across
U.S. Route 50. The parkway continues north along the western boundary of
Washington Dulles International Airport to the intersection of Old Ox Road. The road now goes north towards Loudoun Valley Estates in
Ashburn. The parkway then heads north towards Ryan Road.
Brambleton and Ashburn At Old Ox Road, SR 606 transitions onto Old Ox Road and the SR 607 designation begins for the Loudoun County Parkway. The parkway continues north to a partially-tolled interchange with 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. The parkway meets
SR 7 (Leesburg Pike) at an unnumbered
SPUI interchange. Just north of there, the parkway terminates at an intersection with George Washington Boulevard, which serves the
George Washington University Virginia Campus. The roadway continues as Riverside Parkway, which parallels SR 7 on its north side west towards
Leesburg. ==Major Construction Projects==
