Cyclists this afternoon just put their heads down and muscled on through it. Snow isn't slippery when you're just riding straight. And on a segregrated bike lane, you don't have any other traffic to worry about.
You ride slower, of course. And slow to a crawl when cornering and approaching intersections. But other than that, it's just another day on the bike lanes. In the above photo our bike lane snowploughs hadn't been past, but they came later on.
