bridges stories

This is a terrible, terrible idea. It is, or rather could be, a bridge in Paris (called "A Bridge in Paris") that's made of inflatable tubing and three giant interconnected trampolines. It'll never happen, because people would sue the berets off of anyone who put it up for the injuries that would ensue, but wow, I want this to be real.
There's an old viaduct system in Italy — which is basically an elevated highway or railway — that officials there thought would cost too much to demolish to make it worth it. Instead, they put out a call on how to modernize it. One idea? Install dozens of wind turbines along its length.
