This works great until it snows. Then the above-grade bike lane is generally not adequately cleared, and cyclists are forced back onto the street, which is now narrower by the width of the bike lane.

At grade bicycle lanes tend to be victims of snowplowing anyway, in my experience.

Make the bike lanes wide enough to allow a snowplow to pass. Additionally, plow cycle paths first and more often, as cyclists are more vulnerable to slippery road surfaces.
