ARLINGTON, Va. -- Construction crews move dirt and prepare the ground at the Arlington National Cemetery Millennium Expansion Project, Feb. 19, 2014. The 27-acre project will add nearly 30,000 burial and niche spaces with a mix of above-ground columbariums and in-ground burials. The project also involves restoring an impaired stream that runs through the area. (U.S. Army photo/Patrick Bloodgood)
