Powerful wind-driven snow has forced widespread highway closures across southern Manitoba, including the complete shutdown of Winnipeg’s Perimeter Highway, as near-whiteout conditions made travel too dangerous on Friday. Provincial officials are urging people to delay non-essential trips after blowing snow sharply reduced visibility across several major highways, creating hazardous driving conditions even where snowfall itself was not especially heavy.
The closures are being caused primarily by blowing snow, a common prairie weather hazard that can reduce visibility within seconds. Strong winds lift loose snow from fields and road shoulders, making it difficult for drivers to see traffic, lane markings, intersections, or stopped vehicles ahead.
Perimeter Highway closed around Winnipeg
Manitoba officials have closed both Provincial Trunk Highway (PTH) 100, known as the South Perimeter, and PTH 101, the North Perimeter. Together, these highways form Winnipeg’s main bypass route and are heavily used by commuters, commercial trucks, and travellers moving around the city.
A full closure of the Perimeter Highway is uncommon and signals that road conditions have reached a level where safe travel can no longer be maintained. Officials warn motorists not to drive around barricades or assume conditions improve a short distance beyond closure points.
Multiple highways across southern Manitoba affected
The disruption extends well beyond Winnipeg. A section of the Trans-Canada Highway between Winnipeg and Elie has been closed, while several other provincial routes have also been shut down because of poor visibility.
Closures have been reported on parts of Highway 2, Highway 8, Highway 9, and Highway 236. The number of affected routes shows this is a regional weather event rather than an isolated road problem.

Why blowing snow creates dangerous driving conditions
Unlike steady snowfall, blowing snow can change visibility almost instantly. Drivers may experience clear conditions for a short distance before entering a wall of drifting snow that hides the road ahead.
These rapid changes increase the risk of collisions because vehicles may brake suddenly, travel at different speeds, or become difficult to see until they are only a short distance away. Even experienced winter drivers can struggle when visibility disappears.
That is why transportation officials often close highways before crashes become widespread, rather than waiting for conditions to worsen further.
Strong winds continue across the region
Environment Canada has issued a Blowing Snow Advisory covering much of southern Manitoba, including Winnipeg and Brandon. Forecast wind gusts between 60 and 80 km/h are expected to continue producing drifting snow in exposed areas throughout the day.
Open farmland and highways with limited tree cover are especially vulnerable because strong crosswinds can keep snow moving long after active snowfall begins to decrease.
Officials urge people to delay travel
Provincial authorities continue to advise against non-essential travel until weather and road conditions improve. During blowing snow events, lower driving speeds alone may not be enough to prevent crashes when visibility drops to only a few metres.
Drivers are encouraged to check the latest road closures, traffic cameras, and weather conditions through Manitoba 511 before starting any trip, as highway status can change quickly.
Conditions expected to improve gradually
Forecasters expect visibility to improve gradually from northwest to southeast through Friday evening and into Saturday. However, transportation officials caution that road conditions may continue to be hazardous even after skies begin to clear.
Snowdrifts, icy pavement, and reduced visibility in exposed areas may remain a concern until maintenance crews can clear affected routes and confirm that travel can resume safely. Until then, highway closures across southern Manitoba remain an important reminder that strong winds can quickly turn routine winter driving into a serious safety risk.
