Typically relying on a twig to hold up all of one's weight is a bad idea, that is unless it's a twig bridge, in which case there's no problem. This fully functional bridge draws it's design from the natural look of a fallen tree.
Twigs are some of the weakest pieces of nature imaginable. In nature, it's easy for even the lightest of animals to simply walk on a twig and snap it. This twig bridge, though, might be a bit harder to break. The bridge is designed by UGO architects and takes it's inspiration from a fallen twig in the water.
The structure is made of drawn metal sheets for its base but is complemented by natural elements such as wild plants and white wood to give a natural feel to pedestrians.
