That’s as much a suspension brdige as the golden gate. Same principle, the side ropes in tension support the deck ropes (lower ropes) and provide them rigidity and support through the vertical ties. Mistakenly you may think the side ropes are handrails, but they are there to greatly increase the weight capacity of the lower ropes and provide structural integrity to the brdige deck (lower ropes). As a free bonus they do give you something to hold onto in order to cross.I bet it took them months to make the rope and build the brdige. Us north americans are completely lost when the power goes out, by contrast.
