Paris to have inflatable trampoline bridge across Seine?

Parisians could have an extra spring in their step when crossing the Seine soon, judging by these plans for a giant inflatable bridge.

Designers have unveiled this fun-filled artist's impression of an inflatable trampoline-style bridge in the French capital.

The bridge would be made of three enormous air-filled 'doughnuts', each 30m in diameter, self-supporting and held together to form a series of arches.

Its creators, French designers Atelier Zundel Cristea, say they want Parisians to 'engage on a newer and more playful path across this same water'.

Their design features computer-generated images of pedestrians joyfully bouncing across the unique structure, which they enter via a cantilevered staircase and exit from a slide at the end.

The wacky design was revealed in response to a French competition asking for new bridge ideas across Paris.

Officials in the French capital are after a 'new icon or landmark' in Paris to add to the 37 bridges which already cross its main river.
