Final Design of the New “Certosa” Bridge Connecting Via Volterrana and Via Cassia

The new bridge connecting Via Volterrana and Via Cassia, on Via del Ponte di Certosa in Florence, will replace the current temporary crossings over the Ema stream with a permanent, safe and efficient structure.

The new bridge is a steel-concrete composite structure. It uses braced girders with a parabolic profile and a composite deck slab, designed for high structural performance and long-term durability.

The project also raises the hydraulic clearance and upgrades the connecting road sections. 3D modelling and FEM analysis were used to verify the structure.
