"The driver, a female in her early 30s...serious potentially life threatening condition and the passenger a woman in her late 20s in serious but stable condtiion at this time."
Meanwhile, city road crews are doing their best to keep the streets safe.
Peter Jacoby, who speaks for Calgary's transportation department, says sanders and plows are on call 24 hours a day.
“We prioritize the roads based on the speed, the number of vehicles that are travelling on them and how often they are used at certain times of day and focus on the intersections, the bridge decks, on-off ramps and that sort of thing,” he said.
