On August 2011, a 5.8 magnitude earthquake centered in central Virginia shook the DC metropolitan area, significantly impacting Union Station. The most notable damage was to the historic plaster ceilings in the Main Hall and Retail Concourse. In order to inspect and repair the monumental coffered ceiling, a rolling scaffolding system was designed to allow for the public to continue to safely pass through the station while work progresses above. The scaffolding was in place for several years before the entire ceiling could be secured and repaired.
