A major pileup crash was reported during the Friday morning rush hour in Denver, Colorado, amid winter weather conditions.

The crash was reported shortly before 6 a.m. on November 4 on 6th Avenue between Kalamath Street and Federal Boulevard.

According to the Denver Police Department, about 100 vehicles were involved in the crash.

Police said that no life-threatening injuries were reported. Thirteen people were hospitalized.

While the cause of the crash remains under investigation by police, winter weather was reported at the time of the pileup.

The National Weather Service says that two to four inches of snow fell in the metro Denver area on Thursday night.

The Colorado Department of Transportation (CDOT) told KDVR that the City of Denver is responsible for treating the road where the pileup occurred. CDOT also said that it may have been too warm for pre-treatment of the roads to have been effective.

Both directions of 6th Avenue reopened around 11:30 a.m.

A motorist involved in the crash recorded video as more cars became involved in the pileup (Language Warning).
