Southbound traffic on the QE II south of Lacombe, Alta., has come to a complete stop due to numerous collisions, RCMP say.
Northbound traffic is moving slowly, but sporadically as snow continues to fall, leaving roads icy.
Traffic on Highway 2 south of Lacombe has been at a complete stop this afternoon.
CBC employee Nola Keeler as caught on the highway travelling from Edmonton to Canmore.
Many vehicles were in the ditch, including a truck hauling a horse trailer, she said
"It was completely stuck there and the people actually went and got their horses," Keelor said. "The poor horses were standing there with blankets on them as the snow fell on them and the traffic crawled by in both directions."
The horses were not hurt, she said.
Police say travel is not recommended, and anyone feeling compelled to drive is urged to use extreme caution and expect delays.
