So, what’s puzzling about these images? The first person to get it right will win a box of brand-new, unused semicolons from Brian Fies, or, if the winner is Brian Fies, a box of dots. Real elevated dots, not those newfangled, deflated, tired, lying-on-the-line ones.

Parkes, New South Wales, Highway 39 (left) and Currajong Street. I first recognized the oddity that this quiz refers to at about the location of the light-blue “39” shield in this image in April of 1986, when I passed through Parkes on a little pilgrimage.
Good luck!
