Как чистят хайвей в Канаде

View from my condo window at Yonge/401 watching the snowplows clear the highway. Wish I didn’t have the radio on or you would hear the loud sound, almost like a close airplane, as they clear the highway lanes. Causes quite a traffic backup as get have to block traffic to get started. Would like to know how they do that.. Comment below if you’ve been stopped by snowplows on the highway!
