An amusing factoid: Chicago's famous grid is not actually N-S, E-W aligned: most E-W streets fall south by a bit as you move west. The whole grid is tilted counterclockwise, as you quickly discover when you look critically. Wacker, where this picture is shot is one of the few that do run true, perhaps because as a recent raised street it's a modern artifact, not original to the grid.

I found one blog that accounts for the error and places the tilt at 1.3 degrees: https://drloihjournal.blogspot.com/2020/04/why-north-south-chicago-streets-jog-at-north-avenue.html
