but how would the sidewalk snowplows get around them?

So, in the image isn't actually of a sidewalk, I don't believe, it's just the concrete area surrounding a parking garage ramp.

However, those wouldn't actually be on the sidewalk, in the situation I am thinking of, they would be in the median...ish area between the sidewalk and the road...at most corners, the sidewalks and crossings are not exactly at the corner, but as with bollards they could simply be kept clear of the sidewalk footpath.
