[Posted at 7:51 a.m. ET] An interstate has been shut down for two miles this morning in a suburb of Oklahoma City after more than 20 vehicles crashed in an accident that the Oklahoma Highway Patrol says likely was caused by freezing rain.
The chain-reaction-style accident occurred on Interstate 40 westbound in Del City, Oklahoma, and involved 21 vehicles, including three big rigs, Oklahoma Highway Patrol dispatcher Kerri Markey told CNN. The accident took place at 2:50 a.m. CT (3:50 ET).
Markey said an unknown number of people have been transported to a hospital with injuries characterized as not life-threatening.
The Oklahoma Highway Patrol said they do not know when the highway will reopen.
