This is a partial list of secondary state highways in the U.S. state of Virginia. The numbers begin with 600 and can go into five digits in populous counties such as Fairfax County. The same number can be, and usually is, assigned to secondary roads in multiple counties. Because of the sheer number of secondary routes, this list is not intended to be a complete list.
For information about the creation and history of Virginia's Secondary Roads System, see article Byrd Road Act.
State Route 758 in Lee County extends for 7.3 miles (11.7 km)[5] from U.S. Route 58 west of Jonesville south to the Tennessee state line. Its continuation in Tennessee is an unnumbered county road in the direction of State Route 63 at Mulberry Gap. SR 758 was primary SR 63 until 1946.
State Route 803 in Accomack County, also known as Causeway Road and Wallops Island Road, is a road that connects SR 679 (Atlantic Road) in Assawoman to the Wallops Island Flight Facility on Wallops Island.
State Route 846 in Loudoun County runs for 4.80 miles (7.72 km) from west of SR 28 through Sterling to north of SR 7. SR 846 begins as four-lane divided Sterling Boulevard at SR 1036 (Pacific Boulevard) west of SR 846's partial cloverleaf interchange with SR 28 (Sully Road). The state secondary route intersects the Washington and Old Dominion Railroad Trail and SR 625 (Church Road) within Sterling, where the boulevard has parallel service roads for much of its course. North of SR 7 (Leesburg Pike), SR 846 continues as Cardinal Glen Circle, a lollipop-shaped neighborhood street that curves around and ends at itself just north of the SR 7 intersection.[9]
