Veterans Memorial Highway is the name chosen for the following roads:
State Route 16 is a primary state highway in the southwest part of the U.S. state of Virginia. It runs from the North Carolina border at North Carolina Highway 16 north to the West Virginia border at West Virginia Route 16, passing through the towns of Troutdale, Marion, and Tazewell. Highway 16 is part of a three-state route 16 that connects the Charlotte region with northwestern West Virginia.
State Route 4 is a primary state highway in the U.S. state of Virginia. Known as Buggs Island Road, the state highway runs 11.02 miles (17.73 km) from the North Carolina state line near Palmer Springs north to U.S. Route 58 near Midway. SR 4 connects US 58 with John H. Kerr Dam, which impounds the Roanoke River to form Kerr Lake. The state highway was assigned concurrent with the construction of the dam and reservoir in the early 1950s.
Virginia State Route 234 is a primary state highway in the U.S. state of Virginia. It runs from U.S. Route 1 near Dumfries via Independent Hill as Dumfries Road, bypasses Manassas as Prince William Parkway, and has a brief concurrency with Interstate 66 for 2.27 miles (3.65 km) between exits 44 and 47 before continuing northwest via Catharpin to U.S. Route 15 near Woolsey as Sudley Road.
State Route 606 in Fairfax and Loudoun Counties, Virginia is a secondary state highway traversing the communities of Reston, Herndon, Sterling, Arcola, and South Riding. The road is important not only because it is an inter-county connector, but it goes around the back of Dulles Airport, is part of the Loudoun County Parkway, and it provides a shortcut between the Reston / Herndon area and U.S. Route 50. Although the Herndon streets are not technically part of SR 606, they are signed as SR 606, and they connect to streets that are part of SR 606, thus providing a continuous route.
