Navy and National Park Service officials say repairs to the damaged dock of the USS Arizona Memorial are taking longer than expected, which will delay the reopening of the Pearl Harbor landmark at least a day.

Navy Region Hawaii spokesman Bill Doughty said Wednesday that repairs will continue into the evening and perhaps Thursday.

National Park Service spokeswoman Abby Wines says they hope to reopen the memorial Friday or Saturday.

They initially aimed to reopen on Thursday.

A mishap involving the hospital ship USNS Mercy and two tugboats damaged the floating dock last week.

The Navy says the Mercy may have hit the dock as the vessels maneuvered out of Pearl Harbor. Waves generated by one of the Mercy’s propellers pushed the dock about 10 feet toward the memorial.
