Note: highest, not tallest. Highest should technically be the building here: https://en.m.wikipedia.org/wiki/Kola_Superdeep_Borehole which is more than 12km above ground, that is to say 12km high. Or, rather, was, having been destroyed since. There’s other boreholes too though.

The Kola boreholes are 22 centimeters (9 inches) in diameter, that building is not a bridge in any way, shape, or form.

One of these days I’ll get a model railroad bridge and put it over a borehole. But that day shan’t be today because arguing technicalities on HN seems easier :)
