Manitoba's Infrastructure and Transportation Department reported ice-covered and slippery conditions on the Trans-Canada Highway from city limits east to Ste. Anne on Monday afternoon.

There were also slippery sections and drifting snow on parts of the Trans-Canada heading west, especially around the Portage la Prairie area.

Meanwhile, police in northwestern Ontario had closed Highway 17 between the Manitoba-Ontario border and Vermillion Bay for hours late Monday due to icy road conditions.

The stretch of road reopened to traffic shortly after 7:30 p.m. CT, according to an advisory from Ontario Provincial Police.

Back in Manitoba, roads were also icy on parts of Highways 5, 6, 17 and 59, according to the transportation department's road conditions.

Within the city, the most slippery areas were on Sturgeon Road, Inkster Boulevard, Route 90 through Polo Park Shopping Centre, Lagimodiere Boulevard, and on roads north of the city, the CBC's Trevor Dineen reported.

Temperatures peaked just above 0 C early on Monday but started dropping in the afternoon. The mercury is expected to hit –11 C by 8 p.m., says CBC meteorologist John Sauder.
