Brescia Verona Vicenza Padona highway S.p.a.

The bridge made up by three bays with a rectilinear axis of less than 22 meters span, for an overall length of 62.85m. Built in the 1960s, the bridge was expanded with a project dating back to the years 1989-1990. After this project, the width of the deck reaches the current 34.70 m. Two carriageways with two lanes in each direction compose the road surface. There is also an emergency side lane in the carriageway towards Padua. The work is entirely made in reinforced concrete/precast concrete with deep foundations on poles, frame-type piers with circular shaft, septum abutments with wing walls, scaffolding with reinforced concrete beams in the original portion and in precast concrete in the extension portion. The aim of the project is the assessment of the decay and safety of the bridge.
