Jefferson Memorial Begins $8.75M Makeover

The National Park Service is undergoing a 15-month project to restore the monument.

WASHINGTON, DC -- A lot of work is going to be done on the Jefferson Memorial over the next 15 months.

WJLA reports that the National Park Service has kicked off an $8.75 million project that would involve restoring the monument's roofs, repairing the stone, and cleaning the marble.

Workers will replace the upper and lower roofs that circle the dome so that the building remains dry, and they will lift the marble tiles covering the portico and replace the waterproofing.

Special lasers will be used to remove the black biofilm that dirties the marble on the dome and roof of the Jefferson Memorial, according to the report.

The monument will remain open to the public during the project, although the east side of the memorial will be closed for construction staging.

The project should be completed by May 2020.
