Were you or do you know of anyone that was an eyewitness to this accident. It occurred at 4:00 PM on April 21st. 2009 @ Mile Marker 74 1/2 ... Three Semi's and a Chevrolet Avalanche N/Bound just North of the rest area on Interstate 57. One vehicle was a flatbed carrying a load of steel pipe. That vehicle lost its load and took the cab off of the truck. Again were you a witness to the actual accident or do you know someone that actually saw the accident as it occurred!
