The Washington Monument has closed again due to an elevator malfunction, the second such issue this week.
The monument's elevator stopped Friday afternoon at the 490-foot level after passengers got off at the observation level, National Park Service (NPS) spokesman Mike Litterst said.
No visitors were trapped on the elevator, Litterst said.
Park rangers walked 86 visitors down the stairs.
Technicians are on site to determine the cause of the problems. The monument will be closed at least through Saturday for repairs, Litterst said.
It's the second such problem this week. On Tuesday, the elevator stopped with 19 people inside, requiring them to walk down about 280 feet using the stairs, at least 20 stories. The elevator reopened the following morning.

The monument has been closed at least nine times since May 2015 because of elevator problems. During one elevator outage last May, more than 40 people, including two pregnant women, were trapped at the top.
