In China, they're currently working on the Siduhe Grand Bridge, what will be the tallest bridge in the world when completed. How tall is it? Well, let's just say that you could put the Empire State Building in the valley below it and it wouldn't touch the bridge, with a whopping 360 feet of overhead. So how do you get cables across a chasm that large to build a bridge with? Rockets, of course.

They erected huge towers on either side of the valley to anchor the bridge, first off. Next, they attached 3,200-foot cables to rockets, accurately firing them across the valley to the other side. While other large bridges took care of this process using helicopters or kites, that was just too practical for these guys.

But hey, it worked perfectly, so who am I to judge? The bridge is still under construction, but at this point the really hard part is done. You know, the part with the rockets. Who wants to be the first to drive across it? Anyone?
