Within the cultural-historical part of Trogir, registered on the UNESCO World Heritage List, we are designing a new steel bridge with the idea that it will be more than a utilitarian structure for crossing the sea channel. The new bridge is constructed as a steel shell structure with a variable section in the asymmetric shape of a hyperbolic paraboloid. The highest elevation of the curve of the bridge does not create a visual barrier for rappers in the area of ​​the old city center, and the construction of the bridge itself is extremely thin, light and elegant, so it does not dominate the space and views, but refines and enriches them.

The structural shell has a cassette system made of flat steel, typical for ship constructions (classic ship’s double bottom), inspired by the shipbuilding heritage and tradition of Trogir. A three-component coating with metal powder was used as the finish for the visible parts of the bridge structure, which creates a rust patina under the influence of weather, without damaging the integrity of the structure. Relying on local know-how, the bridge was made in a nearby shipyard from one piece and transported in one day by barge and placed on prepared abutments at the location in Foša.

The staircase is placed along the line of the gentlest ascent on the formed spatial curve, and the treads are designed in such a way as to achieve a significantly gentler slope and a uniform and pleasant transition. The entire surface is made of recycled rubber that invites use and retention. On the steeper parts, there are informal tribunes to enable spontaneous retention on the north side and a perforation in the construction towards Fortin Park with a net for sitting, lying down and playing, which differentiates the park from the urban context. Perforation visually facilitates the construction and achieves a relationship and visual contact above and below the bridge, thus achieving recognition.)
