ARLINGTON, Va. – A second concrete arch is placed into position at the Arlington National Cemetery Millennium Project here March 3, 2015. The archways will support the loop road bridge, which spans a restored stream at the cemetery’s 27-acre expansion project. The project will add nearly 30,000 burial and niche spaces with a mix of above-ground columbariums and in-ground burials. (U.S. Army photo/Patrick Bloodgood)
