China’s rocket-powered bridge
p2pnet news view | Cool:- The Chinese invented gunpowder and rockets so it’s appropriate that they used the latter to build the tallest bridge in the world.
The Siduhe Grand Bridge is, “nearing completion after 4 years of construction in china’s hubei province,” posts Deputydawg, going on »»»
the deck of the bridge has just recently been connected over the valley below and is so high above the ground that you could fit the empire state building underneath it, and still have 360ft spare.
But what’s really interesting (IMHO, anyhow 
) is the fact they used rockets in its construction.
Adds the post »»»
so you’ve erected the enormous towers on each side of the deep valley, deeper than any valley previously bridged. how do you get a pilot cable from one tower to the next? previous solutions have included: attaching the cable to a kite and flying it over (e.g. niagara falls suspension bridge), carrying one end by helicopter (e.g. akashi kaikyo bridge) and floating one end on a boat (e.g. brooklyn bridge). the brains behind the siduhe bridge decided to ignore all those options and break another record instead. they attached the 3200ft cables to rockets and accurately fired them over the valley, becoming the first people to do so.
Cool.
Fancy taking a trip across the valley on the flimsy-looking wood-and-wire catwalk shown in the pic?
