Barry Sullivan, 31, of Unionville was southbound when he ran off the right shoulder of the highway and hit a long flatbed trailer containing a concrete beam, accident investigator Lt. Trey Clanton of the Shelbyville Police Department said.
Sullivan, the car's lone occupant, was in stable condition at Vanderbilt Medical Center in Nashville, where he was airlifted early Saturday, Clanton said.
Rescuers at the scene commented Sullivan was fortunate to survive the crash.
The reason Sullivan ran off the roadway hasn't been determined, Clanton said.
"The accident is still under investigation. We're checking to see if alcohol was involved but it doesn't appear to be at this point."
Several tractor-trailers are parked alongside U.S. 231 near the north exit of 437 Bypass. The trailers contain beams for the new Highway 130 bridge. The beams are being kept alongside U.S. 231 until needed at the construction site.
"There were reflective markers behind the truck. The trucking company followed state protocol," Clanton said.
