After watching this 1960s-vintage British Pathé reel showing how electrical trasmission towers used to be built, I no longer wonder why infrastructure used to be cheap.
Hampshire. An item showing the dangerous job of building electricity pylons. Various shots of half built pylons, a man collects his tools and climbs up the side. Part of the structure is lifted up with a crane and men walk across the arms to fix it into position. Various shots of the giant cable drums, and the power lines running through the cables, a man with a telephone directs them. Various shots as they adjust the tension of the pipe from a suspended platform.
"In days to come, pylons too could have their champions, eager to preserve them as historical monuments."
