HICKORY, N.C. (AP) — Crews have found the body of a construction worker who fell off a bridge and never resurfaced from Lake Hickory.

Authorities say a construction crew was doing maintenance on the bridge over the lake north of Hickory when the man fell into the water. His name was not immediately available.

Witnesses say the man was pulling fencing material down when he fell in the water. Officials say two co-workers went into the lake after him, but were unable to find him.

Crews searched the lake for more than 12 hours before finding the body.

State labor and transportation officials are investigating the death, as is the sheriff’s department.
