The National Park Service says the Washington Monument will be closed for at least the next 10 days as evaluations continue on its elevator after recent mechanical and electrical problems.

The agency said in a news release Friday that staff are evaluating the elevator to learn about the recent failures.

The monument has been closed since Wednesday, when the elevator’s compensating cable broke loose from the car, causing it to stop between the 490-foot and 500-foot levels.

The monument was also closed last weekend after a voltage drop of incoming power. And it was closed for nearly a week in July because of elevator problems.
