A man is dead after he was knocked from his bicycle and over the side of the James Island connector Tuesday morning.

The Coroner's Office identified the bicyclist as 54-year-old Mitchell Hollon of Charleston.

Police responded to the collision in the westbound lanes about 8:40 a.m. after a witness reported seeing the bicyclist go over the wall, spokesman Charles Francis said.

Authorities on airboats recovered Hollon's body from the marsh some 40 feet below about an hour later. The man's bicycle and helmet were still on the shoulder, not far from an AT&T service truck with a shattered windshield and large dent in its passenger side.

Officers also marked several more smaller pieces of the bike that stretched some 50 yards in the shoulder.

Charleston County Rescue Squad members and Charleston police used airboats to access the body from the marsh, about 50 feet from the Wappoo Cut. Among those aboard the boats was the coroner, who has not yet identified the man.
