In 2011, a 5.8 magnitude earthquake sent tourists scrambling as debris fell and the 555-foot tall Washington Monument shook.
When it was all said and done there were more than 150 cracks and many of the structure’s stones had been shaken loose. Repairs totaled $15 million. The fix was a painstaking process given the height of the structure. Engineers scaled the exterior, inspecting 9,000 stones individually.
More than 35 miles of tubing and piping made up this scaffolding that encased the monument.
Now the National Park Service deemed the structure safe and ready for tourists.
