Repair work on the Washington Monument is finally ready to get under way with the last of more than 550 feet of scaffolding in place.
The National Park Service has released helmet-cam video of the final preparations from atop of the Washington Monument.
The monument, the world's largest freestanding stone structure, has been closed for repairs since a 5.8 magnitude earthquake rattled the region Aug. 23, 2011.
The project is expected to last 12 to 18 months, according to the NPS. The total cost of the repairs could reach $15 million.
