An inflatable trampoline bridge that spans the Seine River just near the Eiffel Tower is the top trending destination-related pin on Pinterest.

The only trouble with that is the fact that the destination doesn't actually exist.

The bridge, and the images of it pinned and shared all over the internet, were part of a concept design submitted by architecture firm AZC, for a 2012 contest sponsored by ArchTriumph.

French design firm Atelier Zündel Cristea, who designed the trampoline bridge, took full advantage of the contest to show off his novel idea: Floating bouncy platforms twisted into arches that are attached with a cord to form the trampoline bridge. Stairs at either end of the banks of the Seine River allow access to the bridge, with a slide option for travelers in a rush.

"It appears to us that Paris has the bridges and passages necessary for the flow of vehicular and pedestrian traffic across its waterways. Our intention is to invite its visitors and inhabitants to engage on a newer and more playful path across this same water," Zündel Cristea told Lost At E Minor.

His design placed third in the contest. The winning bridge, named "Water At-traction," is made of steel cables that wobble when people cross it, mimicking the movement of the water beneath it, according to CNN.

Although Cristea's bridge was never built, Pinterest users and travelers alike should not give up just yet.

"We are in touch with different possible clients interested in this concept. Meanwhile, a prototype through which the project was tested has been produced in Spain last November," Cristea told Lost At E Minor.

Since the release of the design, people have been speculating about the safefy issues that are an inherent part of a trampoline installation on such a large scale.

"This is a terrible, terrible idea ... 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," says Evan Ackerman, of
