I put it to you that this is the purest hit, the Platonic ideal, of a certain strand of hauntalogical whatever-it-is. That strand being the municipal, "mildly alien" one. Not overtly supernatural, not overtly sci-fi but somehow suggestive of both. I can't pin down why, exactly, but it hits the spot for me even more than the big stuff - the megastructures, the brutalist icons etc. Those photos of spanking new bridges passing over nowt but grass send a shiver up my spine. Phwoar!
Btw, those last two are of the Hockley Flyover in Birmingham. Do a Google image search of hockley flyover and you get some fantastic colour pics taken during construction, and a bunch that appear to show that all the knobbly bits are still there. Any locals able to confirm that?
