Premier Suspension Bridge Erm, let me see where we are heading to? I see, the bridge infront has anything cool? Yea, it was a premier suspension bridge where still cables are not invented yet during the construction. So back around 150 years ago, the engineer can’t figure out how to build this bridge, so he came out with the idea of steel plates that cut into long small pieces and screwed them together. That time, it was consider a big accomplishment.
