The impact of the wreck split the trailer open and spilled hundreds of boxes of chicken onto the roadway. By the lunch hour crews were still working to clean up the mess.

No other vehicles were involved in the crash.

Arlington police are investigating whether or not the big rig driver fell asleep just before the accident. The man was taken to Medical City of Arlington with minor injuries.
