The Sardinian Grenadiers Bridge, built over the Piave River, takes its name in honour of the ancient Italian Army unit who fought during the First World War not far from the place where the bridge is built.

The structure consists of five spans, two side ones 90 meters long and three central ones 100 meters long. The use of concrete and steel makes the structure extremely resistant to seismic movements and, to give greater protection from atmospheric agents, the external surface has been painted with a waterproofing cycle typical of the naval sector. Particularly important has been the launching of the two sections composing the central span above the river: they have been firstly assembled on the ground and then positioned with a combined operation from the two shores, using a unique crane in Italy with a 800 tons capacity. Part of the 2nd lot of the variant of San Donà di Piave to the highway 14, this bridge has allowed to completely modify the road structure and direct the heavy traffic far from the inhabited centres. The roadway includes two lanes (one for each direction) and passable verges along the bridge with cycle paths and sidewalks.
