Desire path for straight sidewalk
(infosec.pub)
Desire paths Desire paths can be paths created as a consequence of erosion caused by human or animal foot-fall or traffic. The paths usually represent the shortest or most easily navigated routes between origins and destinations. https://en.wikipedia.org/wiki/Desire_path
I'll throw in another $10 that the sidewalk was somewhere else initially.
I'm betting the road was narrower, and the sidewalk further to the left (in the photo). The pole was to the right of the sidewalk. These were all planned/built around the same time.
Then the road was widened. The sidewalk had to be pushed (moved/rebuilt) further to the right. They could've put it far enough over to be completely on the other side of the pole, but that would have other implications - including running into the fire hydrant in the background.
