Visitors to the USS Arizona Memorial will not be able to disembark from their shuttle boats at the memorial itself today but will be given harbor tours nearby because of damage to the loading ramp.

Specialists at the National Park Service are assessing the problem, a crack in the supporting structure for the visitor loading ramp to the memorial, which is accessible only by boat from the Pearl Harbor Visitor Center.

Onshore programs at the USS Arizona Memorial will continue as usual, as well as at partner sites, including the Battleships Missouri Memorial, the USS Bowfin Submarine Museum & Park and the Pacific Aviation Museum Pearl Harbor.

“We will inform the public of any changes to visitor access and make every effort to resume normal operations as soon as possible,” the National Park Service said in a news release.
