Northbound U.S. 17 near Doar Road re-opened late Saturday night after a one-car fatal accident.

The two northbound lanes of the highway were shut at about 10 p.m. because officials were concerned that pilings supporting a bridge over Awendaw Creek may have been damaged by the accident.

Officials said they were not sure when the northbound lanes would re-open. However, about an hour later, the Charleston County Sheriff's Office said the lanes were again open.

Divers found one person dead inside a car flipped upside down in Awendaw Creek, he said.

The identity of the person was not immediately available, officials said.

Officials searched the area to rule out the possibility that others were in the car. So far, no other bodies have been found, Brokaw said.

The incident, which happened at about 4:47 p.m., blocked traffic on U.S. 17 in both directions for several hours.

Southbound U.S. 17 at Awendaw Creek was re-opened at about 10 p.m.

A DOT spokesman could not be reached for comment.

The car came to rest in the creek in about four-feet of water.

A Coast Guard helicopter crew assisted in the search for others who might have been in the car. The South Carolina Department of Natural Resources, Charleston County Volunteer Rescue Squad and Awendaw, Mount Pleasant and Isle of Palms fire departments also assisted.
