Walkerton Bridge, Spanning Mattaponi River at State Route 629, Walkerton, King and Queen County, Virginia

Significance: The Walkerton Bridge, originally known as the Mattaponi River Bridge, is one of a handful of swing-truss crossings remaining in Virginia and an early project conducted by the Virginia Department of Transportation after they assumed control of the county road system in 1932. With the proposed demise of the Great Wicomico bridge, the Walkerton crossing is a manually operated swing that is not assisted by electrical or mechanical power. The Walkerton Bridge has become a rare artifact, representing a type of bridge technology that once was ubiquitous, but now is on the verge of extinction.
