Police are warning drivers on the Trans-Canada Highway about Saturday afternoon crash involving three semi trailers. Icy roads led to the three-semi collision, and subsequent closure of a stretch of the highway.

A stretch of Highway 1 was closed between Moose Jaw and Swift Current running from Mortlach and Rush Lake, beginning Saturday afternoon due to icy, slippery sections, loose snow and reduced visibility.

Moose Jaw police said it's expect the highway will reopen by 5 p.m. CST, though travel is still not recommend. 

A snow fall warning is also in effect for Moose Jaw, with up to 15 centimetres expected to fall over the weekend.  

The semis lost control and crashed with each other due to poor road conditions, police said. 

Roads are currently ice covered, with drifting snow and poor visibility. 

Rough roads a wrinkle for Rider fans

The icy conditions and road closure could make things difficult for Saskatchewan Roughrider fans. Many are expected to make the drive to Calgary for the CFL's West Division Final game between the Riders and Stampeders Sunday afternoon.

If people are heading out they can check the Highway Hotline to see the latest updates on conditions and to help find safe routes. 

Officers are  reminding motorists to drive with caution. People who are heading through that area are also being asked to delay their travel plans by until weather and road conditions improve.
