North Branch Quantico Creek Bridge, Prince William Forest Park, on NPS Route 406 spanning north branch of Quantico Creek, Dumfries, Prince William County, Virginia

Significance: This bridge is representative of a common bridge type that became indigenous to the late nineteenth to early twentieth century landscape of America: a low Pratt pony metal truss bridge. The bridge predates the park's development and existence, yet its present use as a trail bridge is in keeping with the original intention of Prince William Forest Park as a preserved wilderness. As one of the last physical remnants remaining from the mining activities in this region of Prince William County, the bridge can also be linked to earlier land use in the area.
