The driver and lone occupant of a box truck that crashed into the poles of a large sign on I85 southbound near the Peach Orchard Road exit just after noon Thursday did not survive the accident, according to officials.

Identification has not been released as family has not been notified.

The box truck went off the left side of the highway, hitting a guardrail before going over that rail and into the median, striking two of the metal poles of a gantry sign, which is a large traffic sign mounted on a fairly elaborate overhead structure, usually on highways.

The front cab of the truck was split by the impact. Traffic was shut down in two of the the southbound lanes for several hours, with traffic backed up into Spencer, and northbound traffic slowed to a crawl at the same time.

Investigators are working to try to determine the cause of the crash.
