This 400m length bridge (144m length central span and 84m length two lateral spans) is made by three steel arches that support a steel deck by cable stays. Arches geometry follows architectural shape: each arch is composed by 4 legs supported by concrete piers.
Main arches are linked with a hinge detail which allows rotation in longitudinal plane, but guarantees a transversal rigid connection. At apex location each arch has a 25m cantilever part.
The two lateral arches are connected at the top with a CHS profile, that is an hinge restrain with vertical axis, such to improve arches instability resistance under transversal wind load action effect.
