The bridge is the architectural work that best combines the shape rules with the structure and composition ones. The design of the bridge is, in the most classic consideration, a cultural act that has its roots in the ancient triad firmitas, utilitas, venustas, which Vitruvius himself coined, wherein structural form and function coincide.
The bridge is also an object through which we can perceive and experience the place, a unique fact that, through the form exalted by the structure, confirms the true identity of a context. There is also a close link between bridge and perception: in its use, some links from the bridge to the territory and from the territory to the bridge can be created . However, when small and medium sized constructions are concerned, the ability to model the material in all the different directions enables us to create some very special effects, such as reducing the perception of the thickness of the deck or improving the profiles where the roadway intersects the waterway. This requires exploiting the plastic properties of concrete, avoiding those standardised bridge schemes which simply make the bridge rest on its supports, which undermine the opportunity of giving character to the location. The following examples illustrate the approach to the work-context-landscape-suggestions “dialogue”, which is fascinating and which is considered not only in the research into the type as the founding moment for the structural design, but also as a basic assumption to encourage ongoing research into the formal potential that concrete offers in order to understand the meaning and the perception of the infrastructure of the landscape.
