Elevator at Washington Monument is working again

WASHINGTON - (AP) -- The National Park Service says the elevator at the Washington Monument is working again, even though the cause of the most recent outage hasn't been determined.

The park service said in a news release Wednesday morning that the monument was to open on time at 9 a.m. It closed Tuesday afternoon when the elevator stopped about halfway up the 555-foot obelisk, forcing a few dozen people to walk down hundreds of steps.

The park service says it's awaiting a final report from technicians on the cause of the outage. But it says the elevator has been certified as safe.

The elevator has stalled several times in the past year.
