Around 10:10 p.m. Tuesday, the Royal Canadian Mounted Police (RCMP) received calls for a pileup that involved 15 to 20 vehicles in Airdrie.

In the end, a tractor-trailer, five cars, four pick-up trucks, three SUVs and a van were involved in the pileup, the RCMP listed in the assessment of the accident on Wednesday.

The bad weather conditions could be at the origin of this drama, specified the RCMP. Police were also warning motorists on Wednesday of difficult road conditions along Highway 2 south of Red Deer and north of Airdrie. Motorists have been asked to stay home, if possible.

A witness to the scene recounted the horror he experienced to CTV News. Mike Crampton said he saw a semi-trailer on fire and a dozen vehicles piled up. "I've never seen a fire like that," he said. They kept watering it like crazy and it wouldn't go out."

He added that the fog was so thick on the highway that it was almost impossible to see any landmarks.

There is no fear for the lives of the nine people who were taken to hospital.
