Vault Topper
ARLINGTON, Va. – Contractors working at the Arlington National Cemetery’s Millennium Project remove the top off a pre-cast, pre-placed double-depth-concrete liner so identification numbers can be painted in it, March 22, 2016. The liners are a first for the cemetery and will maximize burial opportunities within the 27 acre expansion project. (U.S. Army photo/Patrick Bloodgood)
