I’m no civil engineer so could someone explain the purpose of the four guy wires? --- and ‘to stop it falling over’ isn’t the answer! What I can’t see is how they‘re providing any lateral stability as the angle from the vertical seems too acute for that. As I see it, perhaps wrongly, if the tower cab moved a couple of feet to the left the tension on the right side wires would barely increase. So what’s the answer? By the way, are these the same architects who designed the Millennium Bridge.
