The USS Arizona Memorial will remain dark at night until ongoing electrical problems identified earlier this week are resolved.

The National Park Service said there’s “an irregularity in the electrical ground for the power line that provides electricity from Ford Island to the USS Arizona Memorial.” The power won’t be turned on until repairs are finished, which is taking longer than originally anticipated.

“This means the memorial will be dark at night until work is complete. Because of the darkness, the flag will be brought down at closing each night and raised again the following day,” World War II Valor in the Pacific superintendent Jacqueline Ashwell said.

Visits to the memorial will continue, and the USS Missouri Memorial, Bowfin Submarine Museum, and Pacific Aviation Museum Pearl Harbor are also open as usual.
