The City and County of Honolulu said city crews removed a large concrete structure from the shoreline at Waimea Bay at about 9:30 a.m. today.

The curved concrete piece was deemed a public safety hazard by the Department of Parks and Recreation and the Department of Emergency Management.

Workers used an excavator to pull the piece out of the water and move it up the beach. The city said the piece was too large to remove from the area until it can be broken into smaller pieces.
