KEYSTONE, S.D. — Major construction projects will begin this week at the Mount Rushmore National Memorial.

Construction will continue through this year and much of 2020; the estimated completion date for all projects is late 2020, according to the National Park Service.

The construction will address several deferred maintenance projects and will improve safety and accessibility for visitors. Construction is funded by more than $8 million in federal money earmarked for deferred maintenance projects.

The Lincoln Borglum Visitor Center and the amphitheater are closed because of construction. However, an evening program with a ranger talk, veteran recognition, national anthem and lighting of the sculpture will begin at 9 p.m. nightly through the summer.

Construction will begin eliminating access to the Grand View Terrace and the Avenue of Flags. Projects at the Lincoln Borglum Visitor Center will include replacing the roof, replacing the heating and cooling system, new carpeting, new bathroom plumbing, new stairwells, new elevators, better accessibility and improved views of Mount Rushmore itself, according to Maureen McGee-Ballinger, public information officer.

Despite ongoing construction, there’s still plenty to see and do at Mount Rushmore, McGee-Ballinger said. Park rangers can help direct visitors to areas of the memorial that are open.
