The restoration effort will be the first comprehensive refurbishment of the memorial since it was dedicated by President Dwight D. Eisenhower in 1954, though it has had routine maintenance over the years, said National Park Service Director Jonathan Jarvis.
"These are our icons. We should be extraordinarily proud of these sites, and we want them to look their best," Mr. Jarvis said. "Over time they become a little worn. It's important that we go back in and freshen them up."
