Saskatoon police say they responded to 15 collisions across the city Friday morning, as freezing rain caused havoc on roads in and around the city.

No injuries were reported, though some roads were closed for short periods of time as emergency crews cleaned up multiple messes.

Those included a multi-vehicle accident on Circle Drive, just north of Taylor Street.

A plumbing company van that had rolled over was lying in the middle of the northbound lanes, while another car was in the median and two more badly damaged cars were pushed to the side of the road.

Police cordoned off the area, allowing traffic to slowly continue through in one lane past the area of the accident.

Emergency crews were also at the scene of another multi-vehicle collision on north Circle Drive near 33rd Street Friday morning.

There were no reported injuries, but motorists were urged to slow down and give themselves plenty of time to get to their destination.

Warman RCMP are also responding to a two-vehicle collision on Highway 14, about 11 kilometres west of Saskatoon. One person is seriously injured, while another also sustained injuries. That highway is closed and traffic is being diverted.

Environment Canada issued a freezing rain warning for Saskatoon and other communities along the Yellowhead Highway corridor on Friday.

The risk of freezing rain was expected to ease off around noon, the weather agency said.

Surfaces such as highways, roads, walkways and parking lots may become icy and slippery.

Environment Canada is urging everyone to take extra care when walking or driving in affected areas.
