The District of Columbia's non-voting congressional delegate wants to know why the Washington Monument elevator keeps breaking down despite the millions of dollars spent to refurbish the structure following a 5.8 magnitude earthquake five years ago.

Del. Eleanor Holmes Norton, a Democrat, said she will meet Wednesday with officials from the National Park Service, which oversees the monument and major tourist attraction.

The Park Service announced a 10-day closure last week because of the malfunctioning elevator, which has broken several times this year.

Norton's office said in a statement Tuesday that the Park Service only recently disclosed the monument's elevator panel, which is 20 years old, needs to be completely replaced.

"Norton has been concerned about chronic monument elevator shutdowns this summer and believes it is important for the public to know the reason," a statement from Norton's office said. "She had expected that after repairs to the monument itself following the earthquake of 2011 there would be no more issues with the monument or its lone elevator — but breakdowns have persisted and become more frequent."

The 555-foot monument suffered cracks and other damage that required $15 million in repairs. The money did not cover the cost of fixing the elevator, and the Park Service told WTOP the earthquake damage may have contributed to the problems with the elevator panel by allowing water to seep through the cracks.
