French artist Olivier Grossetête used three enormous helium balloons to float a rope bridge over a lake in Tatton Park, a historic estate in north-west England. (Balloons have appeared in a number of projects we’ve featured on Dezeen, including a proposal for a transport network of enormous floating balloons and a bench that appears to be held up by bunches of balloons at each end.)

All fun until a strong gust sends it a few blocks away into somebody’s back yard. Grossetête “Theoretically strong enough to hold the weight of a person.”

I’m not sure if this counts as a passerelle but it’s pretty neat nonetheless. And it’s from the same architect that designed the Peace Bridge in Calgary:
