A New Bridge over A22 and Adige River in Salorno, Italy

Abstract This report outlines the main features of a new bridge recently completed in Salorno (Bolzano), Italy. The new structure deserves to be highlighted because of its particular structural and aesthetic concept. A bridge with an overall “gull wing” geometry was conceived to provide a unitary solution to the contemporary crossings of A22 highway and Adige River, combining the use of post-tensioned concrete and structural steel, and thereby providing a hybrid and efficient structural scheme. This solution was suggested mainly to solve the amalgamation requirement with the riverbank, to guarantee a minimum bridge depth where clearance constraints were present and finally to identify an optimal erection strategy by reducing the effective span over the watercourse.
