Workers and a crane operator maneuver a precast concrete support arch into position in the Millennium Project area of Arlington National Cemtery in Arlington County, Virginia, in the United States on March 3, 2015. The arch will support a bridge which is part of a road that will provide public access to the site once this new section of the cemetery is completed. The bridge will span a restored stream. The Millennium Project will clear 27 acres of property on the cemtery grounds, and add an additional 30,000 burial and inurnment sites.
