Looks like we have a whole new category of proposed passerelles (here and here and here) and here:
A new conceptual design by Paris-based studio AZC won the “Bridge in Paris” competition … They’ve dreamed up an inflatable bridge that’s outfitted with giant trampolines that allow you to bounce your way from the Left Bank over to the Right Bank.
.
The artist who created the concept image seems to have bodies flying 50 feet in the air (though the scale is a little difficult to determine). Why wouldn’t they just fly over the side of the bridge and into the Seine? And who’d want to risk being whacked by flying bodies?
Trampo-Bridge as “art installation” perhaps, but as a crossing… maybe not so likely.
