Bridge over the Tramigna Stream

The structure consists of 3 spans on a straight axis, each just under 22 meters long, for a total deck length of 62.85 m. Built in the 1960s, the bridge was later widened, with an expansion project dating back to 1989–1990, reaching the current deck width of 34.70 m.

The roadway consists of two carriageways with two lanes in each direction, and the carriageway towards Padua has an emergency side lane.

The bridge is built entirely in reinforced and prestressed concrete, with deep pile foundations, frame piers with circular shafts, wall abutments with wing walls, and a girder deck with reinforced concrete beams in the original portion and prestressed concrete beams in the extension, with a composite slab. The goal of the project is the assessment of the state of degradation and safety of the bridge.
