Widening of the A4 Venezia-Trieste Motorway


The project regarded the enlargement of the A4 motorway through the realization of the 3rd lane, by bilateral widening of the pre-existing lanes, creating new lateral enbank- ments drawn up alongside them. The contract included the sections between Gonars (km 89+000) and Villesse (km106+150) and between San Donà di Piave (km 29+500) and Alvisopoli (km 63+000). The works involved the demolition and the rebuilding of all the connected structures, including overpasses, bridges, underpasses, manholes, as well as the creation of new junctions, tollgates and service area.
