Ponte de la Navetta
This competition entry was for a new pedestrian and cycle bridge to replace the old Ponte de la Navetta in Parma which was destroyed by floods in late 2014.
Our proposal, conceived in collaboration with Ney & Partners, was very simple: two triangulated trusses support a wooden deck for pedestrians and cyclists beneath wooden brise soleil. The trusses form an arc in elevation with the mid-point of the bridge 1m higher than the end points. The truss height also varies from 3m at the ends to 4.5m in the middle.
Simple fabricated steel profiles are used for all members and in elevation the inclination of the struts change. At the ends the struts are triangulated where the shear forces are greatest. In the middle they become progressively more vertical where the bending forces are greatest. As a result the bridge simple illustrates and responds to the forces applied to the structure in an economical and elegant way.
