Document 15: Virginia State Route 13: State Route 13 (SR 13) is a primary state highway in the U.S. state of Virginia. Known as Old Buckingham Road, the state highway runs 24.08 mi from U.S. Route 60 and SR 45 in Cumberland east to US 60 in Plain View.

The state highway is the only state-numbered highway in Virginia that shares a number with a U.S. Highway but does not form a state-numbered extension of that U.S. Highway. SR 13's number comes from being a segment of the original cross-state SR 13 in 1918; that highway included portions of modern US 60. In 1933, US 60 was shifted to its present corridor between Buena Vista and Richmond, replacing SR 13. Two years later, SR 13 was assigned to Old Buckingham Road when US 60 was moved to its present alignment from Cumberland to east of Powhatan.
