(CNN) - The Washington Monument will remain closed for repairs for at least another year and possibly into 2014, National Park Service officials said Monday.
The 555-foot-tall monument has been closed since an earthquake struck the mid-Atlantic region near Richmond, Virginia, in August 2011. Repairs are expected to begin this fall.
The service said that huge scaffolding will be needed for the outside repair work, which will take 12 to 18 months to complete. Some of the repair work will include sealing cracks, removing loose pieces of stone and repairing joints. At least nine of the marble panels on the exterior near the top are cracked, according to a post-earthquake assessment. Others are chipped but not in danger of falling, the report said.
